Similar thread to many, but I need advice on the i7/8GB/256 MBA vs the i5(2.4)/8GB/256 rMBP. I will use the computer as my main machine, but for basic enough stuff. Don't take it out much because I have my iPad for the road. I love the design of the air, but I love the screen of the pro. Would the i7 in the air offer significant performance improvements over the pro? I know it's clocked lower but can increase... I haven't seen any benchmarks yet comparing the two... Is retina really all that? Is it worth sacrificing the design and battery life of the air for? Thanks for the advice.
