The HP48 has a pretty good keyboard. I remember someone who typed as fast as most people would do on a full keyboard, using some weird kind of touch typing with the hands vertically positioned on both sides of the calculator.

The problem is more about the software. The HP48 is pretty slow, and has a tendency to lose your data a bit too easily. There are some editors written in assembly that are good enough though, and since you had a GX, you could use memory card backups.

Yes, the keyboard space was large enough that you could get into a routine of using both hands. Scrolling through the code was a nightmare though, it was not the fastest IDE at the time.
