i'm using the newer Apple bluetooth mouse ...
i didn't think that it was that much better than an older mouse until .. the batteries went out in the middle of the night and i didn't have any new ones in the house .. lol
so, i plugged in a corded mouse thinking .. no big deal .. boy, was i ever wrong
went out within an hour to get new batteries for the magic mouse (what apple calls it) .. and i make sure that i always have extra batteries around the house now ..
it's bluetooth and may work with a Windows PC .. not sure .. i use both Mac and Windows, but dont have bluetooth on the Windows PC so no way to find out ..
