This review seems a little late to the game... Would have loved to see your thoughts on the other new "magic" tools, such as auto-tagging. When I saw this on Jakob Neilsen's blog, I only clicked because I figured it would be on all the newly released features. You really need a part II that deals with auto-tagging, auto-redact, and channels. (Agree on their sentiment analysis... I haven't found it super useful either. I take the "starting point" point to be table stakes...)
