I will be buying a new laptop soon, I was all up for getting a retina MacBook pro but the thought of spending £1650 (edu discount) is scaring me! I need to run Aperture and Photoshop. I would spec the MBA with 8gbs of RAM and possibly a 2.0ghz i7. Do you think I would ever not regret not buying the retina pro because the air was to slow? I would live the pro but it's a heck of a lot of money to spend and I'm not sure running aperture and photoshop would make good enough use of it! I am currently running a 15" MBP 09. Upgrading it is not really worth it either!
