I have a somehwat functional PowerBook G4. Its physical damage is really what limits it (broken hinge). I've decided to get a MBP ( I didn't want the smaller glossy screen of the MB) sometime this week, but need some advice. I was looking at the 2.33, 2 GB Ram, ATI Mobility Radeon X1600 graphics with 256MB SDRAM model initially. I was then thinking, how much of a change in performance would I have with the 2.16, 2GB Ram, ATI Mobility Radeon X1600 graphics with 256MB SDRAM model? The price difference is about $342 (with student discount). Either way, it would be a big upgrade over my PowerBook (1.5 Ghz, 512 MB ram), which has been very frustrating over the last few months. I plan on using the computer for photo editing with Aperture, internet, music, minor video editing with iMovie, Photoshop, word processing, watching videos/DVD's. I appreciate any advice... Thanks!
