I'm currently thinking about getting a MacBook Air and passing down my 2011 MacBook Pro to a family member. There are a couple of questions I have. 1. Has anyone upgraded from a MacBook Pro 2011 to the MacBook Air 2014, seen a big difference in speeds? 2. Would I see a difference in the MacBook Air if I upgraded from the standard 1.4ghz to the 1.7ghz i7? Custom spec on Apples website. Being a student I would get a student discount on the Mackbook Air, I'm considering waiting until Apple also announce their back to school promo. The reason I'm considering a MacBook Air, is because of the 12 hour battery life and the portability. What have your experiences been like for those of you who have moved from a MacBook Pro to a MacBook Air?
