I tested the macbook airs in store with the stock aperture install and stock raw images ,and it tock about 2 mins to load the 33mega pixel image. and was even slower with simple edits like highlights. Then i did the same on the macbook pro 13, and the image loaded like it had an ssd in it, and adjustments were as smooth as butter! Will the i5 Airs perform like this or will the uvl chips although being i5 still cripple it, essentially? Thanks Im interested to see if anybody knows YET!
