I use a MetroCard mousepad that New York's MTA gave out when they were trying to hire people to work in the subways.
It works fine with my optical mouse.
I don't see the big deal about so called "gamer" mouse pads. What do they do that my free one does not?
Edit: I'm not trying to be a troll. I'm just curious why someone would spend more than a few bucks on a mouse pad.
