Ya I forgot to make it a poll

Anyway I prefere a ball mouse(logi with the wheel)
over the optical. This is my reason:
When you start going off the mouse pad & have to pick up the mouse & scoot it back to center the ball remains still. When you do that with a optical the eye still reads(because you dont pick it up very high) causing your view to go haywire !!
I just wish that logitech would would make a ball(usb) version of that cool new optical, the buttons are smooth!!!
