ill probably be getting a mac pro soon hopefully. part of my thinking has been about the choice of wireless or wired. i already have a wired set with a white keyboard/mouse(though its not a mighty mouse) so im interested in the wireless set. how does the battery life last? i usually leave my computer on from when i get home until i go to bed even if im not using it. does it have a way to save battery power if i havent used the computer in the last X minutes? anyone got any pointers for me? thanks!!!
