getting started with CP/M 2.2 on the MinZ-C tiny computer

This video shows the steps I learned while getting started with the MinZ CP/M system that I bought on Tindie. The system is designed and built by Circle M systems and is based on the Z180 CPU a fully compatible descendant of the Zilog Z80.
In this video I:
Provide a brief overview of the hardware
Configure terminal emulation for command line access as well as file transfer.
Demonstrate utilities for transferring files between disks as well as between CP/M and PC.
Demonstrate the use of User Areas for file management, as well as demonstrating how to move files between user areas.

Maybe I'm just an idiot, but what's the point of this little computer? As far as I can see the only I/O is that USB serial connection. Why wouldn't I just emulate a CP/M machine?
