Is it hard to do a touch keyboard on devices like this?
At this size, yeah. It's tough to make touch keys large enough that you don't tap multiple buttons at once.
It also takes a lot of processor IO, and generally a dedicated cap sense peripheral as well. Plus, many of those peripherals have a scan interval that's laggy when you get to large IO counts.
