i've had to thrown away two microsoft intellimouse, the usb connector eventually gets ****ed up by using the ps2 adaptor, and just won't work in the usb anymore. and another one just by regular usage, and couple bangs and the mouse doesn't work. yet i still use one ms intellimouse for a couple months now and it works perfectly. i have a memorex, and two other 5 dollar optical mouses, and they work just as good.
