Here here! All my hand tendon and wrist problems went away when I started using a thumb-based trackball. I've used both Logitech and Microsoft - no real diff (except the MS one has more buttons). The problems seem to go away when you stop moving your wrist and hand altogether, just using your thumb to move and fingers to click. It's a pity they seem to be getting rare - I have a couple stockpiled.
