For multiple tasks some times it would be beneficial to achieve results faster if you could move with either one ball or utilize both making the pointer a more accurate and easier tool to navigate the screen with. Some times the top track ball is not as accurate, but is faster so we simply move the pointer to the screen's desired position and utilize the bottom track ball for correct placement in exactly the right place. When you get used to using a two-ball system you would be much faster at point and click saving time. Also, you could set it to do only one or the other for those who are only used to one kind of track ball mouse.

Reward: Maybe a track ball that is also a clicker button when pushed down on.
