I hate mousepads. They slide all over the place, they stain, and they start to smell funny after a couple of keg parties. Mine usually sits on the opposite side of my keyboard, with a drink on top of it so I don't ruin the finish on my desk. Frankly, I never even saw the point of them after the advent of the optical mouse. Back in the days of the trackball I understood it, you couldn't get those damned things to work on any other surface.
In reality, before the world of hardcore computer gaming came along there really was no need for the mousepad for the optical mouse. Nearly any surface would do the job. But as mice got better, and their DPI resolution improved well into the thousands, your standard desktop surface just didn't do the trick anymore. So people like Nova came along and decided to make sure you were getting the most out of your $75 mouse.
