they can, XP will install the drivers automatically and away you go, but the older style apple mice only have one button so they are virtually unusable with a normal PC (no right click)
Some of the older Apple mice just have a single button. This'll appear as left click. Since right click is so important under Windows, it's pretty useless.
Apple's Mighty Mouse (shipped for past few years will all iMacs) does have two buttons on it, and can be used as a two button mouse under Windows.
(But the Mighty Mouse is the most awful mouse ever made and no-one should use it, in my opinion.)
cossieboy - the reason i want an apple mouse is because i have a white pc with white keyboard, mouse etc and my mum doesnt want anything else but white lol
But I still see the Mighty Mouse as worse, because it purports to be a two-button mouse, when its functionality is totally flawed. At least the burger mouse just did what it said.
