My hand surgeon had me get a touchpad because "clicking" hurts the arthritis in my hands.This doesn't help much. Its responsiveness varies--sometimes it's fine, sometimes it does nothing. Then I have to reach across with my other hand and click the button anyway.I can't select anything with it, either. This is a nightmare.Finally, not a good solution for hand or finger pain, because you have to tap it pretty hard and sometimes repeatedly, for it to respond.I wish a true ergonomics expert would address this need!So, I'm using it for casual things. But if I really have to get something done, my mouse is still plugged in.
