Used to have a Genius grey optical mouse with little scroll-wheel thingy, wired, but it's right at the end of my table so it kept falling to the floor, finally it fell one too many times and it broke (You could hear parts of the mouse rattling if you shaked it xD) so now I use an old mouse I used before. It's a beige wired Logitech ball mouse (as on bottom: "First / Pilot Wheel Mse") and has a scroll wheel but only 2 buttons. Go scroll wheels xD At school in my class, there are 2 computers, one has a Microsoft IntelliMouse that doesn't work very well and the scroll wheel is all greasy and the other mouse is an OEM (?) with no scroll wheel. The best mice are optical with scroll wheels. xD I love them!
