Hey, Im a college student currently using a late 2007 Macbook with 2.2GHz intel core 2 duo with 1 gig of ram. Generally I only use a computer for word, powerpoint, pdf viewing, watching movies and itunes. For time to time I do use photoshop and dreamweaver for some light web design but nothing to intensive at all. Right now the Macbook isn't cutting it at all. Im considering the 13 inch MBA 1.8 Ghz with 8 gigs. Should I notice a large increase in performance ? Or would I be better off going for the pro. The main thing drawing me to the air is the better screen res.
