Trackball
Does trackball operation involve the thumb? Possible arthritis in thumbs?
Yes. using the thumb for me is so precise. With the right mouse speed settings, you can be very precise and also cover multiple screen real estate without requiring absolute minimum arm movement. Hand rests on body of the devices - no clutching or griping that aggravates carpal tunnel or arthritic conditions.
