I find them a lot more comfortable to use all day long because you don't wind up moving your arm and wrist around on the table like you do with a mouse. Your hand stays stationary on the trackball and your fingers do the moving. Much better than a mouse if you are starting to show signs of carpal tunnel syndrome (sore wrist, numbness in the fingers, etc.). And I also use the Logitech Trackman Marble FX. I've been tempted to buy a couple extras to keep them in reserve when Logitech stops making them. They are great. Chris -- Christopher S.
