yes, the mouse is terribly precise. nailing perfect headshots while strafing like mad is a lovely thing, and probably impossible on a pad. but i can't play doom 3 for more than an hour without my left hand turning into a twisted, aching claw. and the hunched mouse/keyboard posture hurts my shoulders as well. my shoulder and hands take enough abuse from my guitar - is there, like, a pad i could use? that would be properly compatible? and reasonably precise? i'm not particularly interested in multiplayer, so a sacrifice of precision for comfort would be tolerable.
