I found that using a trackpoint and 3 physical buttons has eliminated any carpal tunnel like pains in my hands.

While the touchpad on MBPs is nice, I found clicking a button which isn't a button quite stressful on the hands. Also, moving my hand to the touchpad and then back up to the ASDF-JKL; typing position is uncomfortable having gotten used to just moving one finger to the trackpoint.

The trackpoint does have one major flaw though - drift. Sometimes, it seems to move itself and you have to correct it. Apparently there is some kind of calibration going on, but it's quite annoying and I wish/hope there is some kind of fix.
