To the owners who have the 2.2 or 2.3 model with the high res option. would you give up your 2011 model for the 2011 macbook air? I know a LARGE majority of new air lovers are people who gave up the 13". Lets be real, the 13" isn't that much of a powerhouse but to the 15" owners. would you give up your GPU/high res screen/quad core/larger screen/HD FaceTime to go SUPER portability and semi powerful (for a machine that size) processor?
