Row, row, row your mouse, Up and down the screen. Verily, verily, verily, verily Tradition Solutrean. This is a biased and opinionated sales pitch for trackballs in lieu of mice. I recommend to all my friends that they toss their mice in the trash and substitute a trackball. And such people probably need one of each.
Mice have lots of problems.
Clicking or double clicking without moving the pointing is difficult with a mouse because the buttons are on the moving part. Conventional rolling-ball mice pick up dirt and debris off their pads and, since the encoders are held onto the ball by minimal springs, then skip or just stop working. But the friction between the bottom of any mouse and its pad makes precise pointing difficult. I once saw a mouse with a teflon underside and a very large glass- smooth pad with very little friction. This was a definite improvement.
