Hey, I'm moving the mouse but the pointer isn't going much of anywhere! What's wrong?! Oh yeah, the mouse isn't CORRECTLY ALIGNED with the mouse pad! I'd better check if the mouse pad has moved out of its proper position on the desk. And pay a bit more attention to how I'm holding the mouse so that I don't introduce too much rotation about the vertical axis. That alignment was something I never had to worry about with any type of mouse I used before or after. On the other hand, it worked pretty well when it was lined up right. It really seemed to track motion more smoothly and accurately than mechanical mice. For those who don't understand why it had to be aligned, Wikipedia has an article (https://en.wikipedia.org/wiki/Mouse_Systems https://en.wikipedia.org/wiki/Mouse_Systems) with two good photos.
