> Does that mean that with the kind of trackball you describe you'd have to move your whole wrist to move the ball left and right?
The trackball is fairly large, about 5.5 centimeters in diameter. So I personally use mostly finger movements with slight flicks of the wrist. However, the ball is so large one could keep one’s wrist rigid and use both shoulder and elbow to move it.

It really is a very comfortable device.
