The kinesis board is very cool. 'spensive though ?

Alex, I can not really use my index finger on my right hand due to RSI. So I've learned to mouse mostly with my left hand.

The setup I found most useful is to have two mice - one left and one right. I use the MS Intellimouse on the left for precision work but the Apple mighty mouse works well on the right because the finger can be totally relaxed when pressing the mouse - you end up using your palm mostly.

Plus I find scroll wheels essential on both mice.

hope that helps.
