I ordered my 17 inch powerbook and the rep tried to get me to buy a wireless mouse which I would like but... If there is already bluetooth built into the machine, why would I get a usb plug transmitter to have to hassle with every time I want to use an external mouse? So, I am looking for a bluetooth mouse that will work with Jaguar. I don't know why they would be so hard to find. You'd think apple would put one out. I want the mouse to just work ever time it is near the powerbook.
