I've been using the UHK with a trackball thumb module[1]. I haven't touched a mouse since I got it. It's not as eye catching and futuristic, nor wireless, but a sturdy keyboard and it paid for itself by not having to go to physiotherapy for the past five years (for RSI).

Interesting, that looks too spendy for my taste honestly but I can see a way to justify it. I use a trackball for some of my CAD work but on another PC I sometimes have to check things in CAD, rather than real work, and a ball like that could be a good way to do it.
