Hello! Should I get the Retina MacBook Pro or a Macbook Air (256 Drive, 1.8, Intel 3000) and an iMac 500 gb, 4 gb ram, 512 graphics. Basically, I love the light weight of the Air and it would be nice to have a computer at home for the Apple TV streaming and doing Photoshop, Logic Pro, and Final Cut because of the big screen. I can also wait for the refresh of the iMac. The Retina MBP will be less expensive, and probably light enough to lug around. Advantages and disadvantages of the choices?
