Spent some time on this a while back, and even wrote a driver that let me use a game controller as a complete replacement for my keyboard and mouse. Interesting but not really successful.

One key takeaway: The input bitrate that a competent typist can get from a keyboard is quite high. As a guess, it might be 8x higher than with a gamepad or mouse.

And as an additional detail, I've had more RSI issues with mice than keyboards over the years, even though I use emacs.
