FWIW, before moving to a notebook trackpad exclusively about 5 years, 
I used of track ball to prevent any starting RSI I was getting, as 
far back as 1996.  Specifically the ones with optical tracking.

Nowadays, the right click / scroll trackpad of MacBooks (using two 
fingers instead of one) helps me even further, as it significantly 
reduces the number of mouse moves and key presses.
