Was just wondering what options are out there for someone looking for a bluetooth mouse. I don't like USB dongles and since most Macs have bluetooth built in, it seems like a good idea to take advantage of it. I saw Microsoft's Mac version of its notebook mouse at Best Buy, looked pretty decent. Anyone use one? The only other BT mice that I know of are one logitech one and the Mighty Mouse. Personally I like having a couple of side buttons on mine, which I believe the Logitech lacks. I've used the Mighty Mouse before, not interested in getting one.
