ok, i go away to college, and left all my old pc stuff up there (printer, mouse, etc). i am home for summer now, and purchased the mac down here. i have only been using the trackpad. when i go back to school (and have access to my old stuff), can i use the old mouse i was using with my old pc? would the right click function of the mouse be disabled? or lets say i accidentally right click (old habits die hard) would it just work like a normal click like the mac utilizes? or should i just not use a mouse at all?
