"I use a Microsoft Optical Mouse, and am pretty happy with it."
Same here. It'll do for now. Is it true that wireless mice use batteries? I read that on the back of a mouse box at office max.
"i hate mice with extra buttons...I have an optical Gigabyte EzBrowser...only 2 buttons and the wheel-(button)"
I don't really like those kind either...you may wind up actidentally pressing one that you programed to, say, shutdown the comp or something (although I'm not sure why someone would do that) =)
