I currently have a late 2011 15" MBP and am thinking of switching to a MBA as soon as I can. Its just too big for my current lifestyle (traveling, writing) and the 10-12 hour battery life of the MBA would be a godsend. But I'd like some advice before I buy anything. Since the MBA line just got updated, I'm looking into the 11" but I'm wondering about processor and ram. If I max to an I7 and 8gb of ram would that affect battery life? I'd prefer the full 10 hours. And I guess another thing that's bothering me are the rumors of the new 12" retina. I am able to wait for it, if the Fall 2014 timeline seems correct, but I am wondering if I should? I would probably seriously appreciate the screen, but I remember when the first MBP retina came out they had huge price premiums and people were complaining about screen quality. I'm also worried about the battery life of a new one. I know broadwell is supposedly more energy efficient, but do you guys think it would have less battery levels than the current ones because it may need a stronger processor for the retina screen? I'd have to sell my current MBP before I can purchase anything, so the longer I wait, the less its worth. I guess I'm asking if anyone has more educated speculation or can help me weigh my options better. I would really appreciate it!
