I'd really like to get a Bluetooth mouse for my MacBook, as I really don't like the dongle hanging out the side of my machine for a IR style mouse. Is the Mighty Mouse really the one to get? It looks like it might be really 'big'. I don't really need super fancy, multiple button, phazer gun, super mouse... but I just don't want anything hanging off the side of the laptop. Your advise and experiences are appreciated.
