I am starting to think of replacing my aging macbook pro with something newer. I definitely want to stay at 13". The way I see the this comparison: Reasons to get macbook air (in order of importance) - Battery life - Weight/portability (BTW, does it need to be removed from the bag at airport security?) Reasons to get macbook pro (in order of importance) - Resolution of macbook air not sufficient (I don't think I really need this, but I'm hearing that the 1440x900 resolution will seem ancient once I move to a retina display) - Better specs (Intel Iris graphics, faster CPU, can be spec'ed with more RAM) Are there any other reasons I may be missing? Which screen would have less glare? I mostly use the machine for email, web-browsing (and videos), and occasionally write simulation programs that run for several days continuously. My current laptop gets quite hot when watching videos or when running simulation programs continuously for a long time. I also find it feels slow when browsing, mostly because of the flash/video ads (text pages load quickly). I'm hoping to address the browsing speed issue by upgrading. I plan to sell my current machine if I get a new one. A question about warranty: If you buy a machine with the superdrive accessory and also get Applecare, would Applecare cover the superdrive, or does it only cover the machine? Would appreciate any insights folks have to offer.
