"Other Options"1.5 starson by kenneth0624
Pros: I don't see any.
Cons: Easier and better option available.
Summary: I have severe debilitating arthritis in my right shoulder. For years, I have been using a Logitech Trackman Wheel trackball (Logitech P/N 904353-0403 904353-0403, about $30). My hand NEVER moves; the thumb controls the ball and the fingers rest on the buttons. An added advantage is that no matter where the cursor is, you never have to lift up the mouse; simply rotating the ball will bring it from one edge of the screen to the other (you can also set a [Ctrl] function to find the pointer). I especially like the ballistic effects (slow movements are precise, fast movements are gross).
