Usually, I am simply a passive observer of these forums but today I have an important decision to make that I am literally obsessing over. I'm buying a Macbook Air for my girlfriend for her birthday, but I'm trying to decide between getting a July 2011 and a brand new Air with a spec bump. For $300, there doesn't seem to be too much of a difference between the two, except that the new one has USB 3.0 and the Turbo Boost. Keep in mind, my girlfriend is by no means a power user. She generally sticks to her word processor, netflix and iTunes. Can anybody see a reason not to save a little bit of cash? Please, I need convincing.
