A warning: I switched immediately to a Kinesis keyboard after first getting wrist pains. But Kinesis keyboard uses the thumbs (much stronger digit, right?) to press the modifier keys usually pressed by the little fingers.

Not a good move for me: despite eventually going off all keyboards and using voice dictation software, I have permanent damage in both hands and my thumbs are the first to start hurting.

What I've been told by experts is that the best thing to do is to switch among different layout keyboards every couple of days. Each uses slightly different muscles, and if you switch often enough, you may not fatigue any of them--but there are no guarantees on anything!

yeah, there's alot more emphasis on using the thumbs for the most repetitive motions. interesting idea to keep switching. I'll have to give that a try.
