In the market for a laptop for light Logic Pro work. Sessions I can take to my iMac later. Seeing as people have been using 15" MBPs for mobile work since 2000 I figured that any new MBA would also suffice. Is anyone using a MBA for mobile audio work in Logic or some video work with FCP? Will the June MBAs be a lot quicker? Should I buy a 15" MBP instead and swap the optical drive with another HD or something?
