I might pick one up. The USB cable on the standard Mac mouse is a bit of a pain. For whatever reason, it doesn't seem capable of just sitting there quietly and staying out of the way. It always seems to be sending exploratory loops across my keyboard's numpad. But, since it is too short to plug into any port other than the one on my keyboard I've just put up with it. It's one of those minor annoyances that is just enough of a pain that it bugs me but not enough of a pain that I actually do anything about it. Maybe the wow-cool factor of a bluetooth mouse will inspire me to do something about it. Probably not, but hey, you never know.
