HP Prime vs TI-nspire CX II CAS | Review and Comparison

[@stingoh]

I really like that you are covering a niche topic, and doing so thoroughly and in depth. Your review really has a lot of substance.

[@respectbigman3133]

We can tell from the get go that this guy is a bias HP prime user. Grifting for a company is not unbiased reviews

[@traviswalker8933]

​@@respectbigman3133you have a bias for TI because it's clearly seen that they didn't make a good calculator here.

[@jonm7547]

This reviewer is absolutely right in his assessment. I am an older professional mechanical engineer, and recently I thought I should better refresh my rusty maths, as well as getting familiar with these newer maths tools. I bought all three (TI nspire CAS, HP Prime G2 and Casio fx CG 500) and I can confirm that HP appears way better built than the other. I actually like the TI quite a lot, especially when with all the alpha keys you can enter directly the functions and operators easily (as well as having way more tutorials and learning materials. But the overall first impression is that long term I will focus on the HP which seems to be better built and more professional (as opposed as just a school teaching device). It is still very early stages for me, and things may change.

[@diegodominguez205]

ik its 11 months ago but what would u recommend

[@odarge]

and today which one you prefer ?

[@markw208]

@Jon M, I’m in the same situation and thoughts. Although I’m recently retired I’m intrigued by and curious about the newer calculators. A long way from my old Picket Circular Slide Rule 😁 or TI SR50. From the reviews I’ve seen so far I would have thoughts similar to yours; the features you use daily would differentiate between 2 very capable calculators. The choice is so difficult I think I will buy both.

[@Jojo-be3cf]

Tested the HP… it has a lot of bugs. Crashed multiple times. Also it does not support selection at all. Want to insert a division mid in the equation? It is not possible! The software of the HP feels rushed and unfinished. Also the App-Concept is pretty stupid in reality. Will checkout the nSpire now. Also, the RPN of the HP is a marketing thing. It is only availible in the numeric/home mode, but not in CAS, which makes it a useless feature for me.

[@NeedBetterLoginName]

@@markw208 Hi, Mark. Don't forget to consider the Ti-89 Titanium. It's still the best calculator in practice if you are not a student. Has the killer feature of always turning on instantly, rather than sometimes needing to boot.

[@bradryan4041]

TWO points that you missed. 1) The HP advanced graphing app is an IMPLICIT plotter, thus you can plot an equation in open form ( sin(x*y) = x^2 ) whereas on the TI you could never plot such a graph because it has to be in closed form ( y = ). I cannot overstate how much of a huge advantage this is over the TI. 2) Whatever person chose to put the letters and certain symbols on the the HP Prime White Keys in ORANGE should be FIRED !!! They are very hard to make out in various lighting conditions. Incidentally, I have all three ( HP Prime, Nspire CX II CAS, and the FX-CG500 ) love them all and enjoy using them.

[@mgobluevictor]

I agree on the color of the alpha keys. One important detail is that the Prime with G2 hardware has an updated KB and the color/contrast of the orange is much better than the first gen hardware. There was also a revision of the hardware prior to G2 that improved the orange coloring on the keys, but didn't include the improved processor. The Prime in this video appears to be the improved KB, but I am not sure if it is the G2 hardware or not.

[@Jake-ux9cq]

You can do implicit graphing on the Ti. You just need to click on the escape key when you create a new function.

[@ti84satact12]

You can absolutely do implicit graphing! Just switch from function to relation and you can graph almost any relation. Extremely useful when you want to graph relations versus functions!

[@AJFreeway]

Awesome review. I would say I definitely prefer the HP Prime in terms of speed of processing commands, the ability to adjust the graphing window quickly with the touchscreen, and the library of built-in functions is much more robust, and I prefer the TI Nspire for its full keyboard and ease of creating functions on-the-fly. I will say that what the Prime lacks in descriptions of its error messages it makes up for with its substantial Help feature for every built-in function. For deciding on one or the other, it mostly depends on what it will be used for. The HP Prime is probably geared towards more advanced mathematics while the TI calcs seem to be made more for the high school and early college students. I wouldn't say either is particularly great for programming, since even with a full keyboard it's sort of a pain with the TI Nspire, and I prefer coding the programs on an actual PC and transferring them to the calculator, but it's basically impossible to do it with the HP Prime's lack of a keyboard. Side note: The HP Prime actually does have a partial derivatives template located under the templates key (the one located to the right of the toolbox button).

[@powertube5671]

Thanks so much for an excellent video, which led me to purchase the HP from eBay for a reasonable price. I've owned the TI-nSpire for a number of years and it has spent most of its time collecting dust and losing charge. When I did use it, I found it to be so cumbersome. I spent some time following a tutorial to learn the features and found the overall human factors engineering was terrible. I'm delighted to come across this HP prime comparison video, which shows how easy the HP is to use. I was shocked to see how much slower the TI is than the HP. Just for curiosity sake, I programmed that summation into a few lines of BASIC in my own written BASIC interpreter. I designed and programmed the expression evaluator, which, internally uses RPN. The interpreter executes many lines of C code for the operation. I am pleased to say that that same perceived speed on the interpreter is instantaneous. Of course, I am using it on a fairly new PC. One of the most difficult things to do on the TI is to scale a graph down to see more of it. The use of the visual hand grabber is a challenge.

[@ti84satact12]

I’ve always used the Texas Instrument calculators and never considered anything else but this video has me second guessing my loyalty! Right now I have lots of programs and tools built around TIs but I have lots to consider! Thanks for the comparison!

[@tyronekim3506]

This was a very helpful comparison. I have always thought HP was better built than TI and you confirmed my belief. Thanks.

[@eduardouresticharre6873]

Excellent review! Thanks for sharing. Over 30 years of being a teacher at a University in Mexico, I had been using TI for over 15 years, after HP almost leave this market (I used de HP 48 and 49 at the beginning of the 90s) and I was very happy with TI (I am retired now). I really liked the use of documents, the sheet classes, the programming style, the primitive functions about probability distributions, the inclusion of LUA and now Python programs, the emulator software, and the easy way to share documents (some of my students make documents for each homework or exam). The "solve" command in TI surprised me when I was looking for a limit in a definite integral in an arc length formula. And maybe the most important thing is the TI community, which is very active in some countries, particularly in Australia. I really hope HP company will think the CAS calculator market at the college level is important. Again. Thanks!!

Hola disculpe, podrias ayudarme? Tengo una duda con las calculadoras

[@bsodmike]

I checked a couple of the other reviews and yours is by far the best, thanks for touching on hardware and build issues. Seems the TI supports Python scripting but given how underpowered it is, I’m not going to hold my breath. Ordered the HP. Thanks!

[@JacksonBenete]

@@ElissaLee1 Sometimes you want to have a "routine" or algorithm that you keep repeating over and over again transformed into a program so you can call it with just a few key presses. But the HP Prime also supports micropython which is pretty much python anyways, so I don't think TI would be better just because of that. I would like the calculator to support C and Assembly though.

[@lywzcx663]

Well you can create documents with HP Prime. It is just that they do not call it document. In the Apps menu there is a Save button which is in my opinion the exact same function as documents.

[@bryan_hiebert]

Nice comparison! I was surprised by this iteration in the Texas Instruments line-up. The processor speed variance is significant and the touch screen and resolution of the HP looked way better. The document system in the TI appears to be very "clunky". A few things you didn't touch on was the pc/computer interface between the calculators, what programming languages (python is currently supported on the TI as opposed to the HP's Prime Programming Language (PPL)) each calculator supports and any accessories or add-on each have which you could do in a later video or update this one and how those things might affect a person's decision.

[@ConstantGeekery]

Very useful comparison, thank you. These models are significantly faster than the Casio fx-9860GII that I use.

[@EEEp0w3r]

I am also a professional and needed a calculator that didn't involve more computer use, more versatile, so I chose the ti nspire. Definitely not disappointed. I bet the HP is good as well.

[@martinhawrylkiewicz2025]

Really like this review! I honestly feel like a good graphing calculator should have most used dedicated keys for trig functions, logs, exponents, etc available without being forced to look for them in sub menus ...I have been using my old HS calculator TI 83 Plus but am really impressed by HP Prime! The ability to just punch on the screen to zoom on the graph....wow!

Now I know to save a few bucks and go with the HP Prime G2 instead of the Nspire CX2 CAS.

[@tylerarrigoni7700]

Nice comparison. I used to be an avid HP48 user through college. I didn't do enough research and just bought the Nspire CX II CAS. I agree with you on all points. I hate going thru menus and 2nd order keys for EE, etc. Keys are tiny and cheap feeling. It's an extremely capable device, but all your points are exactly what I missed about my old HPs. The old HPs were SO SLOW...even for the day. But the input and so fast and well laid oout. I may cut my losses and get the HP and give this to my son.

nice video. going to get the HP. had one in college in the 90's and miss it!

[@panhandlejake6200]

I had my first HP calculator 47 years ago - the predecessor to the HP45. That calculator was a basic scientific calculator that used HPs RPN notation. It used the same keys as the current Prime and lasted many years. I upgraded to the programmable HP29C and eventually to the HP41CX. All were great for their time. I am currently using the TI84 because I work with high school math students, who use the TI -- but I certainly prefer the HP platforms. I wasn't aware of the CAS and will look into it. I have currently been using Mathematica online - which obviously has much more computational capabilities.

[@mbunds]

Your production is exactly what I was looking for. I will be purchasing the Prime!

[@peocaveo]

If you think that navigating through the menus is annoying (TI), for example if you need the SIN function, you can always type "sin" with the extended keyboard... That's why there's a keyboard and a sin button is not available...

[@gregmag66]

Most important thing as someone who got his electrical engineering degree in ‘89 ( think HP41CX and after working a bit, the HP 48GX, my personal favorite), the HP does RPN, a must!!

[@zcqm]

This video actually helped pick the calculator I'm going to use for high school, HP prime all the way!

[@AnnaVahtera]

I'll agree with you mostly, and the Prime is looking really good, BUT. The last bit about the keyboard. That entirely depends. Not all users want/have to use trig functions every single day, or that often at all, but may use the calculator extensively for programming (and/or note taking). Programming or taking notes on a standard calculator keyboard is agony. Menus are another choice some makers use for things, but I think the TI's solution of single button with quick menu is the best. Dedicated buttons take too much space and reserve spots from other functions that could be used instead. I much prefer the TI's one-button-menu for functions grouped together - HP could've done this even better with their touch screen capability. Click a button and tap screen. It's only a fraction of a second slower than dedicated button, uses way fewer buttons (thus releasing space for other things). I really hope HP would come out with a "Prime II" model that had full keyboard, touchscreen and dedicated group buttons instead of individual. TI can go cry in a corner with their touchpad though, I hate it. Even the clickwheel of the old nSpire was better. The HP is so much better in almost every other way, but with it's "this is the way calculators looked in the 1960s" keyboard it's missing quite a lot of potential, in my opinion.

[@nicholasblumling2117]

Tough choice, personally I like the physical key layout on the TI (lettered keys). If you every had to translate real world functions into a calc it is way easier to use the actual variable starting initial than have to back translate x, y, z, t variables for respectively a kv value or delta P, etc. Torn. Yes you can do that with the Prime, Rs and other letters, but the TI has is down for high level work. Note: the trig button is way better like this, having the ti-89, you are always looking for the dedicated sine, etc button this has it in one place. Personally, this is way better thought out in terms of layout.

I have both the HP Prime G2 and TI nspire CX II-T CAS. Personally, I get on better with the HP. I find it much easier and more logical to use. Working with it is also much smoother, because the TI generally works much slower. The battery life is really better with the TI. Especially if you haven't used both calculators for a long time. The HP is nevertheless empty after 3 weeks (so when you come back from holiday, always remember to recharge). The TI can be left unused for 2 months without any problems, but the battery is still only minimally discharged (the TI seems to have a deep stand-by mode, because it has to reboot first). I would still buy the HP Prime again and again. For me personally, it has the best overall concept (also with regard to the software for the PC).

[@belabaksay-roka900]

Hi Everybody! I’am from Hungary! I have owned an HP Prime G2 for a little over 1 year. And for a good month, I also have a TI-nspire CX II-T CAS machine. So I have a basis for comparison. My verdict is: It is simply true that the HP Prime G2 is more manageable than the TI-nsire CX II-T CAS. (Mainly the reason for the touch screen.) It has roughly 33% faster CPU than the TI-nsire CX II-T CAS. (Prime has a CPU of 528 MHz, while the TI-nsire CX II-T CAS has a clock of 396 MHz.) It may be easier to program than a competitor's machine. But! ... But HP Prime IS AN UNRELIABLE SHIT! Because in the most unexpected moments, your system will COLLAPSE! And then 'FORGOT' all the apps I've developed for it before with great effort! (Short usage functions, longer / programmed / function algorithms, programs, etc.) And those applications in the vast majority of cases already allow you to press RESET to become available, because they disappear from the MACHINE WITHOUT TRACE!… In such cases, only one you can restore my self-developed applications from a backup file saved on my laptop. However, short usable functions and matrices are NOT returned to HP in this way, because HP specifically ‘handles’ them and does not yet discover how to ‘handle’ them, meaning I just have to ‘DREAM’ AGAIN at that time!… The TI-nspire CX II-T CAS doesn't show a predisposition to similar 'meanness' yet, but I'm still distrustful of him who 4-5 years ago already had a TI-nspire Clickpad that died exactly 365 days from the date of purchase. me! After all, irreparably! ... (The term ‘planned obsolescence’ is not a strong enough term for this ‘phenomenon’…) So right now I’m in the process of reloading materials saved from the former TI-nspire Clickpad (still in time) to the new TI-nspire CX II-T CAS and trying to ‘transplant’ the materials from the HP Prime G2. … Then I look forward to 365 days again with mixed hope Concluding remarks: For my part, I wouldn’t really recommend HP Prime to anyone! I say: UNRELIABLE SHIT!

[@cyllansse]

yes, there are many comments like this. The best of HP is the 50G . and the casio fx 90-E (or fx cg50) or the casio classpad never died.

[@JacksonBenete]

At the same time that I believe everything you've pointed out, because there's no reason to don't believe you and because I've read similar comments before, I also think that you might have been unreasonably unlucky. haha I guess that sometimes "shit happens". I always heard of how Apple products are so good and reliable, and how Apple Care is so insanely good, fixing or changing products for new units even years after the Apple warranty expired. I've bought an iPad Pro, and after exactly one year it died for no reason (never discharged, baby-sitted the thing), Apple support doesn't knew what happened either, and they charged me twice the price of a new one "to fix". Gave Apple a second change some years later and I'm happy with my Macbook Air M1, it's really a great product. I guess sometimes we're just unlucky. I'm about to order a HP Prime G2 because in my country any other older calculator either is not available or is more expensive than a brand new Prime, so no reason to expend 200+ dollars on a 40 year old device while the Prime is powerful and not bad at all if not a bad batch/unit. I was about to buy the 50G, it's a bit more than 100 dollars in my country, but I think I would benefit from the graphing capabilities of the Prime, I think it's great for studying, and CAS is also great. If I can have a mini Wolfram Alpha in my pocket, I'm in. Let's see if it'll fail be as well. What calculator you're using right now after 1 year of your comment?

You are not being nit-picky; TI has always tried various keyboard layout system, which is yet to match the original Ti-83. Remember the Ti-92? While if felt like a cool gaming system, I still preferred the hp48GX system back in the days. Perhaps the attempt is to squeeze it all into a standard form factor. The thing is that they all got it right the first time as calculator where not really designed around the QWERTY key layout; I could type as fast on the chronological keys. Oh how I wish the hp had retained RPL programming though. Nothing comes close to that to date. Great video by the way. I always loved the calculator for their differences, and offcourse accepted the limitations. The Ti-85 took a bit further in the string manipulations; however, it was still no where close to the hp, without jumping into machine programming. Though they did their things in the past, and lead the way before the smart devices, such as windows, palm, sybain and android. I still wonder the future of calculator. The main idea is to be simple yet intuitive and sophisticated as needed.

[@400_billion_suns]

Nice video! One clarification at 12:14 : When you open different apps on the Nspire, you’re creating new pages in the *same* document. This is actually a very useful thing if you’re working a complex problem, because any functions or variables you create on a calculator page can be used on a plot page, or spreadsheet data can be used with a stats page, etc. It keeps all variables, calculations, functions etc in one multi-page document that you can save and return to later, and every page has access to stuff you’ve done on other pages. If you open a new document, you get a fresh environment without any saved variables, data, etc. I made use of this feature in my master’s degree for documenting some homework and even transferring it to the PC app where it could be printed. The spreadsheet app in the Nspire can solve equations recursively within its cells, which is something even Excel can’t do (unless you want to use VBA and solver macros).

@@MrMarcec85 so keep in mind that cg50 doesn't have CAS but can offer exact answers and simplify radicals. Ti 84/Ti 84 plus CE can't do that. I would say HP Prime>Ti n-Spire>Cg 50>>>Ti 84 plus CE. Some exams do not allow CAS systems, in that case Cg 50 is both the cheaper and best option. Ti 84 CE is overpriced garbage, literally my 20 Euro scientific calculator can expand stuff like (1+sqrt(2))^3 exactly but the Ti 84 won't and will display just useless approximations. HP Prime is obviously "better" than the Cg 50 since it includes a CAS but you would have to make sure it's allowed in exams (it isn't where I'm from for example). Hope this helped!

[@MrMarcec85]

@@federicovolpe3389 hi thanks! Yes it is a good point of view. I don't need and want CAS. HP is probably the best option but costy and probably too much for my needs. Casio is the best choice for my purposes, for a graphic calc at least! Thanks

[@darioeufrausinodesousa4055]

HP PRIME 👍👍👍👍👍👍👍

[@MusicFanatical1]

The HP seems the clear winner although I prefer the font & display layout of the TI. HP just needs a "prettyfy" routine to make expressions look nicer (e.g. italic letters for variables) like Casio does.

[@mikemullenix6956]

Excellent comparison, and good reasons for using the hp .

[@erlexar]

HP Prime all the way. I recommend it for surveyors or building commercial field engineers. Get it with the SGS Cogo license.

[@Primitive_Code]

10:15-11:00 of the video I think is one reason why the TI-Nspire is the better, more expensive calculator. The fact that it does Numerical Analysis and Differential Equations is huge, although the HP has the ODE solver but that's not enough DE. The TI's python is a more sufficient way to programming. Also, I didn't see Prob & Stats on the HP but I'm sure it's capable since the basic TI-83 can do it. I'd say that for everyday use, the HP is good since it's really fast, but the TI has more ability and is a necessity.

[@MichaelB598]

The character keys on NSpire are very useful when you calculate a term multiple times. On Prime you need always to switch to alpha when storing a variable and the orange characters are very difficult to read when you wear glasses or have bad light conditions.

[@Markus2801A]

In my opinion - as we are using Ti Nspire since many years in School - they haven't changed significantly anything since the first release of the black Ti-Nspire! Thy didn't make big upgrades regarding performance and screen. so I Think Casio ClassPad II und HP Prime are much more powerfull and progressive than Ti Nspire Series!

[@luethboy]

Thanks for the Review man. It was very helpful.

[@Pennine_Lad]

A superb, insightful review, many thanks!

[@georgeentertainment7185]

The perfect calculator would be a combination of the best features of both. That is why understand when some people wrote they'd buy both. It had been great if CASIO fx-CG500 had been included in the comparison.

[@GolerGulch]

I would like to see a video on storing electronics equations like for resonance,xc,xl, etc. I bought a HP27s in 1988 and it just died 4 days ago and that calculator made it so easy to put complete formulas with letter titles. You could solve for any of the variables easy. This was way ahead of it's time and too bad it didn't become a permanent part of HP's line up. This is my reason for requesting a video of how you can store electronic formulas which would give me the confidance in buying one. Otherwise I'll just buy used HP27s's off ebay, thanks.

[@JohnLee-bf2ux]

Randy yeah me too have the same use and not for academica

[@rickymayne2298]

Check out this page and you’ll thank me later! youtube.com/@rolinychupetin He has a lot of videos on writing electronics functions for the HP prime, much more than you would ever wish for. Enjoy, Merry Christmas 🎄

[@hifijohn]

My first calculator was in the mid 70's a sears electronic slide rule with 40 functions and a memory! all for only 80 mid 70's dollars.

[@ugynify]

What is the main difference between TI-nspire cx ii cas and TI-nspire cx-ii t cas?

[@dcloudsync]

The t version is "test" version. Some features are disabled to be allowed for tests in the us. Thats what i have gathered. And it looks pretty with red.

[@rudyperez2542]

wow bro this really opened my eyes

[@Crente1978]

Thank you for the video. I've never had a HP, but this one looks very good. Maybe I'll look out for one... Honestly, I think you've missed TI-nspire's goal, that is to work with different pages in the same document, relating diverse applications. I really enjoy working with it, since the fist one. TI-nspire is much more than a graphing calculator, it's a whole ecosystem. (The alphabet keys are very useful for programming (in python our TI-Basic). Doing that with another keypad is a lot harder.) Now, if you are looking for a calculator just to solve quick, small direct and unrelated questions, maybe investing in a TI-nspire is not the best option.

[@Jack.35.]

OHHHHHH that makes a lot of sense and makes sense why people buy it. And why the ti Nspire series still commands a high price even a decade later. Thank you.

[@thekinection424]

@@Jack.35. simply put: TI is the household brand, therefore everybody who needs a calculator will probably buy a TI. since TIs are also required in many final exams, they can charge high prices because of their demand. Since everybody needs one, they have to swallow a premium for it.

[@DarkarBlmlv5]

One of the most important and relevant thing about the HP Prime, is that HP is still uploading uptades and making better the system. TI isn't doing that.

[@muhammadsteinberg]

Can't speak on what was happening a year ago but as of today you can upgrade Ti (89 titanium, nspire cx cas and nspire cx ii cas). I have the Calc's I mentioned and have just upgraded 2days ago.

[@RealEverythingComputers]

thanks - clear explanation of the differences

[@menzoberranzam]

Awesome comparison! Great video!

[@김유리-t2o]

I was also thinking about these two products, and I think it helped a lot. Maybe I should decide on hp. Do you still think hp is better?

[@gonzalomamani4119]

Can the HP prime save long calculation files or test calculations for later use or editing? I think if he doesn't, it would be a great weakness against Texas.

[@markw208]

I’ve also always preferred HP’s buttons. They have a more positive and solid feel. TI should have improved their key feel long ago. I had a TI-55 II years ago that had schizophrenic keys, sometimes working correctly on 1 click, sometimes requiring another click, sometimes double-clicking itself.

[@froilanrivero2826]

AFAIK CAS can be disabled in the TI, otherwise it wouldn't be certified for certain tests, you probably have to go through some menus to do that. As per the keyboard well this is more like an all-round Calculator, a whole ecosystem for STEM which includes programming for which a full keyboard can come in handy. Anyway it was a great review maybe the HP is better for field trips where you just need the calculation ASAP and not just the other features, maybe they can complement each other.

[@bolleke702]

Nice comparison!

[@dooda1193]

good,,, pls suggest which machine can do indefinite triple integrals

[@ultrametric9317]

The summation test is a little deceptive. TI's CAS is based on Derive, a CAS for DOS/Windows that went through 6 versions. This does sums by first creating a large vector, then summing the elements of the vector. That is inherently slower than HP's approach which is likely just term by term. But the Derive approach is far more useful in a CAS context rather than just crunching numbers. If I want to crunch numbers I pull out the HP-50g which is similarly optimized for numerics. In practice I use Derive to manipulate Clifford algebras with their matrix representations. To put up with a slower summation formula is worth it because the CAS in Derive is absolutely superior in flexibility. You should point out the context of CAS vs. crunching. Also, it is almost surely possible to recast the TI expression to work around the CAS's limitations as a number cruncher.

[@Falken78]

I do not care for the track pad on the TI either. It looks a little weird, but with a USB A female to USB mini male adapter you can hook up a mouse to the TI and use that instead. It makes working with the calculator a lot easier. If you do this, be sure to get a "mini" adapter and not the more common "micro" adapter.

[@stef1196]

Yeah! Like Jean Edouard I am asking : what about the g2 ?

[@N.A._McBee]

Well done comparison! - Although I have both calculators for more than a year, this was quite interesting to me. The feel of the HP Prime is indeed on another level than the overall plasticy feel, sound and look of the TI. The choice TI made with respect to dedicated function keys (where's the SIN button?) irritates me exactly like you. And the question at the end of the day is: Why should I pay more money for the TI if it is definitely between 4 and 6 times slower than the HP and has the clearly lower build quality? - Thanks for this nice video!

[@dienersamuel1]

I think it has to do with the fact that it’s more popular. Same with Ti-84 plus ce to Casio fx cg-50. Simply put, you are paying to have someone to turn to when having problems. However, with the hp prime’s built in help system, you should be able to figure stuff out on your own.

[@JacksonBenete]

I'm getting used to see your comments on calculators videos. hahaha (And I have seen your videos too!) What do you use more often? Your HP Prime, DM41X or the DM42? (Or any other)

[@N.A._McBee]

@@JacksonBenete Hi, funny comment :) But seriously, the DM42 is the one I use most often, when it comes to a series of calculations. Don't know why, but somehow the overall appearance and the display layout may be the most important factors. Next comes the DM41X. - The HP Prime as well as the TI-Nspire don't play a role in my everyday life. The TI takes much too long to boot and to get ready. And the Prime does not have the classical user interface of the old days like the DM-series and the DM42. - Have a good time!

[@alasdairniven6578]

7:39 which one gives the right answer? They are different.

[@adanlara9980]

Could you mention the model numbers? I looked up HP Prime and there are several models. Maybe links as to where I can find these sold? Thank you!

[@alexchambers6208]

That summation wrecked my TI-89 Titanium, but ya know what, I'd keep using it even if you gave me both of these calculators. I love it, and I think it still has more functionality.

[@gate9595]

I agree!

[@JJ-si4qh]

Okay, I'm jumping ship to HP

[@mariomatteopapetti3221]

For the developing of engineering apps what would you suggest?

[@felicytatomaszewska]

It is pretty clear that Texas Instruments basically benefits from the captive market of students because most of the STEM teachers use it so Texas Instruments does not need to put too much effort and can charge whatever it wants.

[@SoundSpeeding]

Is this the HP Prime G2 version that you have?

[@ekifi]

I like Texas Instruments as a brand but the N-Spire series is just ridicolous. It's such a shame they're able to mantain their dominant position while selling likely the worst graphing calculator around for pretty much the highest price. Both the O.S and hardware would need a huge refresh to even start thinking to return competitive. But they don't economically need to do that so i think we'll just keep getting horrendous products for insanely high prices until Casio successfully penetrates the U.S market too.

[@some-one-else-r]

Okay definitely HP Prime is better after seeing that graph test

[@jaime4990]

Thanks!! I love this comparison... Can you compare a symbolic definite integral, like $\int_0^\infty e^{-x^2} dx$, in both calculator? I think HP Prime is superior to TI nspire here... (I apologize for my english, it's not my native language)

for some reason i bought the hp prime ti nspire cx 2 cas and the ti 84 plus ce and the ti 83 plus

[@yalezhang8831]

When calculating the sum with 60k terms, the Nspire is more accurate. It appears it's slow because it's calculating symbolically, which is overkill for engineering. Anyways, still glad I got the superior HP Prime

[@jb42jb]

Did they stop making the HP prime? For some reason there aren’t many sellers selling it new and the price is up around $130
