Hi, I really want to buy either the 12 or 15" powerbook. I've always had windows computer and hate them. But i don't know alot about Mac's. If i get a powerbook for college i'll be on my own with any problems But when i emailed the College's computer guy (just to make sure it would work) he freaked out. "you cant use it on our network or access the internet with it on campus, you need to stay with PC/Windows format." Is he right or does he just not know about Mac?? HELP!!!!!!!!!
