I go to school at the University of Florida and I need something that is easily portable and light to take to classes for notes and looking like im busy in a really boring lecture. I'm holding out for the MacBook Pro's for sure, just not sure if I'm going to need the 15" or not. Eventually, I would like to get a G4 PowerMac for video editing and media storage, so it's not going to be a desktop replacement. I was wondering, all you PowerBook users, do you find a big difference with the weight and screen size? I know it's only about 1lb more for the 15", not sure what the difference on the MacBook Pros is going to be. What are your thoughts?
