Hi all, I'm a Mac user of a few years but I'd still like some advice regarding my next upgrade. I'm currently using a basic MacBook which, after a few years, is running slow. I'm looking to upgrade and am stuck between a MacBook Pro and a MacBook Air. I'm keen on the Air because, obviously, it's very portable and I imagine I'll be taking it around a lot for work. The high-end Air's spec isn't too dissimilar to the 13" Pro, but as I intend to run Photoshop/InDesign/Illustrator on my new Mac, I wondered if people could let me know their experience or if they think the Air will be up to the job of running CS4 smoothly? I'm pretty sure it will but any tips or advice would be much appreciated.
