I’ve got one of these, and my mother for the longest time used it for note taking in church. If you think of it as a PalmOS “laptop” you’re close to the user experience, but really most of the appeal is in the surprisingly good keyboard and the few apps that supported the wide screen. The built-in word processor naturally leverages both of those things and it does it pretty well. Battery life is also quite good, though the backlight can be expensive. Mine uses a Palm SD-Bluetooth card for connectivity.
I wouldn’t mind something like this that hooked to a pi-zero. Terminal only.
