I recently got a Mac Pro - I've been using it for like 2 weeks and it's great. I can't seem to get used to the Mighty Mouse and Keyboard though. My mousing hand (right) is killing me. My entire forearm is sore and I've actually started using my left hand for mousing. It feels stiff and fatigued. I have fairly normal sized hands. I'm 6'1 and not overweight. How does everyone else like the keyboard and mouse? I have a fairly shallow desk and a 30" ACD. Maybe I need more room, maybe I need a gel wrist rest?
