I have a 1.0 GHZ iBook right now. It's fine, but... My dad wants to by my iBook off me, because he wants one, but doesn't need the latest and greatest and I am taking advantage of the opportunity to upgrade. My question is, can I expect a Powerbook (either 15 or 12") with at least a 1.25 GHZ G4 to last me four years of College even with the new intel deal? Just need a little more assurance. Thanks!
