Hello. I've been suing a 15" MBP for 3 years, but it's so damn heavy and I can no longer be arsed to hurt my back by carrying it. I need a MBA fairly quick, so was wondering if the stock 13" 1.3 with 4gb RAM will be enough, realistically, for web and iOS dev? I run XCode 5, Coda, Sublime text but also Photoshop and Illustrator. It'll not be used for anything other than dev, no gaming or large music collections etc. I'd order a custom one online but they just told me it'd take 3-4 weeks. Cheers.
