I have a late 2007 MacBook Pro (Santa Rosa) 2.2Ghz, 2GB Ram, 120GB HDD. Beautiful machine, runs perfectly never had problems. But i'm starting to feel like its getting old, plus I mainly use it for interent, word processing, and occasionally for Photoshop. I'm wondering if a newer MacBook would better suit my needs? Would I be able to sell this for enough money and not have to but much into buying a MacBook?? OR am I just being stupid?
