I will be a college freshman this fall and can't decide whether to get a 12" Powerbook with Superdrive, or a 14" iBook with Superdrive. If I got an iBook and upgraded the GB to 80 and upgraded the MB to 512, I would have basically the same computer as the Powerbook. Except that the iBook only has 1.33GHz and the Powerbook 1.5GHz, and the Powerbook's screen would obviously be smaller. I don't want to spend $300 more for a 15" Powerbook either. Is a 12" screen too small? How much faster is the Powerbook? Which should I buy? Any advice would be great. Thanks!
