Hey all. I have a 2008 Macbook unibody with a 2.0 GHZ processor. I want something more current so i'm looking at a MBA. This will be my primary computer and I mainly want it for music recording/production through Logic and Reason as well as daily internet, photo's and converting the odd movie. My budget basically allows for the 11 inch with an upgraded i7 processor or the standard 13 inch with the i5 processor. Where do you all figure my money is best spent?
