Ok so I start college this fall and I will be dual majoring in photography and graphic design. I recently got a scholarship for $6000 at out bookstore and since San Jose State is a Apple Authorized school I'll definitely be looking into a Mac. I was thinking of getting the 20" iMac with 4GB of RAM for my dorm and the low-end MacBook Air for class and carrying around campus. Would both of those computers be able to run all Adobe software and Aperture without problems? Or would it be better to just get a 17" MacBook Pro? Any help would be appreciated.
