I'm in the market for a new laptop. This is mostly for travel and using away from my home office, where I will have a new Mac Pro or an iMac. I won't be doing anything serious on it: just web browsing, iPhoto, maybe some occasional Lightroom and Photoshop. I was leaning toward the 13" MBA, but the retina display on new MBP is very appealing, as is the thinner/lighter design and improved battery life (9 hours). On the other hand, the 13" MBA will now get up to 13 hours on a single charge, which is pretty impressive. How much of a factor will the retina be in your decision? I haven't used a retina display much, though I've seen one in the store of course. Is it worth going for the MBP and sacrificing a little battery life?
