Hi Everyone, I just purchased a powerbook 1.67, and would like to have a mouse with it should I may find myself needing to use it at home. This may sound like a silly question but does the Apple BT Mouse make the PB run hotter? In other words, does it make the PB work harder, than say using a regular USB mouse? Or is it a nuisance in terms of changing batteries all the time? I would appreciate any help you can give me! Thank you!
