I'm currently thinking about returning my freshly bought rMBP 13" (i7 2.9/8GB/512GB SSD) and switch back to a fully-loaded 2012 MBA and need some feedback if I'm doing the right thing. I'm a professional coder/web developer/screen designer doing a lot of work using the Adobe Creative Suite, Sublime Text, Transmit, Terminal/SSH-Sessions and Parallels for 1-2 virtual machines running Windows for browser testing. My primary work machine in my office is an iMac 27" (maximum BTO configuration i7/8GB, upgraded 128GB SSD as an additional system volume myself). I'm still pretty happy with that, no problems so far, esp. not in regards to performance. Traveling and taking the thing to my clients happens a lot, so this actually is an issue to consider, too. My primary mobile/at home machine was a LATE 2009 MBA 13"/2GB/128GB SSD since 2009 and buggying me performance-wise in the last months. So I got the new rMBA 13" when it came out and am working on it several hours a day for a week now and still not sure. Actually I REALLY like the screen and the option to switch between resolutions (using non-system tools like QuickRes). Performance is great, though I do notice some lagging now and then that wasn't there when browsing the web even back on my 2009 MBA. That's not just my imagination, I put them side by side. What bugs me the most: form factor - the sharp edge on front is actually a problem for me. I think it feels uncomfortable and harder while coding longer times compared to the MBA. The position of your hands while typing was much more relaxing on the MBA keyboard many apps, esp. Adobe CS 6 is not retina ready yet and the UI is really pixelated ugly Battery runtime is worse when running scaled resolutions - maybe not always, but I noticed about an hour less when running with HiDPI 1680x1050 450$ more for just the display - but actually less screen estate when running in retina mode compared to an 2012 MBA the 300g more weight actually does bug me a little. Even though it's not much but coming from the air still seem a lot. It just feels more "bulky". Even though the Air is a bit larger it's actually easier to carry around. GeekBench & Co do not show much difference in performance between a maxed-out 2012 MBA 13" (i7/8GB/512) - anybody here working on both and can say the rMBP is faster? I'm feeling like I'm beeing ripped off - calling this a 'Pro' without dedicated graphics and 16GB RAM for that price did not bug me when ordering first but does the more I think about it. Finally, do you think once you go Air it's always Air? ;-) Actually I think it has a lot of emotional reasons, too. I thought about getting the maxed-out MBA for weeks - then the rMBP was released and I ordered it in a hurry. But to be honest - somehow I miss the "Air" feeling. Are there others around thinking about returning the rMBP or who already did and want to share why? I'm also interested in feedback of others doing the same kind of work that kept it or returned it.
