Hi all!
My father has been using a touchpad to do AutoCAD work for over a year now. (Don't know how I didn't see that sooner.) I gave him a cheap Logitech mouse to use in the meantime. He's right handed and has quite large/wide fingers, so something a bit larger might be just what he needs. He's a palm/hybrid palm gripper. Doesn't need to game or anything, just AutoCAD. Doesn't really care about wireless either, but one fewer cord on his already crowded desk can't hurt.
Thanks!
