I purchased a 2013 MBA 13" i7/256/8GB that is still sitting at home waiting for me since I am out of town. As soon as I get home Saturday night, I'll test the battery life since 12 hours is a big deal to me. I also own a 2012 MBA that gets 7 hours battery and was always wanting more hours since many public places I work at do not keep outlets or do not have enough outlets anymore. With Mavericks due in the Fall, it is not surprising an updated specs 2013 rMBP will be out at that time as well. The price difference between currently between an MBA with my above-listed specs and a base rMBP shows that a rMBP is $50 cheaper. The only difference is that doubling the rMBP from 128 to 256 flash drive will make the rMBP $150 more expensive. Considering student discount is $100 from a rMBP and $50 for an MBA, the price difference becomes a mere $100 to get a same spec'd rMBP. If this holds true or becomes even cheaper if 256 becomes a base standard in the Fall rMBP, then it becomes more of a challenge for me to decide between the 2013 MBA and 2013 Fall rMBP. Here is what is making me indecisive... -Not the weight, but looks. Lets face it, these are Apple devices and looks matter. A lot of people say the .5 weight is negligible, and sure.. I agree its not as big a factor but many forget to mention the looks. But I like the look of the tapered-down slim MBA more than having its thickest part be the standard around the whole rMBP. It looks much more "fatter" or "thicker" when you have to see that thickness from every angle compared to the cool, tapered design of the MBA. Many people don't like the bezel of the MBA, and I would love for it to be eliminated too, but i don't find the bezel as bad as the all-around thickness of the rMBP (and that's even after they finally slim it down to the MBAs thickest point, its currently thicker than even that). Winner: MBA. -The screen. I don't find the MBA screen as bad as some posters mention here in the forums, but I really would love to have the retina screen of the rMBP. Just like I see the screen everyday, I also see the computer's design and looks everyday... so this becomes a difficult decision from this standpoint. For the same price (or $100 more), should I go for the better rMBP screen if all other specs are updated this Fall (including battery life updated to 12 hrs)? I think they'll be able to get the battery life to 12 hours, since all 2012 models (aside from the 11-inchers) had equal battery lives before introducing Haswell computers. Winner: rMBP. So that's it, those are my two biggest concerns between two equal spec'd MBA and rMBP: A) $1600 after taxes and student discount for a 13" MBA i7/256/8 with 12 hour battery life and a slim-tapered design with up to 3.3GHZ turbo-boost, but lacks the retina screen. -or- B) $1600-$1700 after taxes and student discount for a 13" Fall rMBP i5/256/8 with approximately 10-12 hour battery life and a thicker all-around design with 'at least' 3.1GHZ turbo-boost, but has a retina screen. ???
