i'm using trackball for years, it takes far less desktop space than a
mouse and you can cover a much larger screen area without lifting it
around James
(it is a kensinton orbit trackball)

Another angle on the mouse discussion.
All mouses have one thing in common. They require frequent use of the
muscles that lift the arm (deltoid, trapezius, etc). Anyone
experiencing
regular stiffness or aches in the shoulder or neck would be well
advised
to consider using a trackball. It does not require as much use of the
muscles mentioned, as the palm of the hand, and thus, the arm may
remain
at rest while the fingers do the work.
Kensington makes the best trackballs. <http://www.kensington.com/>
