<<A smooth, dark wood grain desk works wonders with an optical mouse, and it's "free." Besides, there are lots of uses for a mouse besides playing Quake that require a high level of precision.>>
Are you trying to tell me the free wood grain can be more precise than, say, 3M Precise Mouse Surfacing? Im on an optical and nothing feels better than 3M if precision is your thing, I switch to Everglide when I need to frag people's ass, the sUrface is perfect for both because its double sided.
