ibook: http://www.apple.com/ibook/specs.html powerbook: http://www.apple.com/powerbook/index15.html i'll be using it for school, movie and photo editing, among other things. but my biggest concern i guess is that i dont want it to be obsolete any time soon. im looking at the 14.1" ibook(1ghz G4) and the 15" powerbook(1.33ghz G4). both are G4's and the biggest difference that i can see is the front speed bus and the speed of the ram in each. what would you advise?
