My friend got $1150 for his, I'd say that's pretty great. And $1000 is pretty damn good too, you'd never see that kind of resale value on a Windows laptop.
Yes, you're right on that one. Regardless of rumors, I'd definitely sell before they got released.
When I was recently fighting off 15" rMBP mojo, I was disconcerted to learn that I could MAYBE get $1100-1200 for my ultimate 2011 13", and that was with Applecare and a bunch of extra stuff thrown in. And by disconcerted, I mean :censored:.
Keep in mind a few oldtimers might have an outdated concept on mac resell value...it used to be Apple updated the powerbook from a 1.25 to a 1.33 ghz g4 chip, so you could get 90% of your value back after a year! Not so anymore, consider it the downside to Apple getting on the Intel upgrade bus.
Anandtech mentioned lagginess and scrolling issues in its review of the rMBP...abysmal under 10.7, improved with 10.8. And that's with an Nvidia 650 card! The culprit seems to be the integrated 4000 graphics powering the display in low power mode.
Since the MBA isn't going to get a discrete GPU due to size constraints, a retina won't happen with Ivy Bridge. Haswell and especially Broadwell are supposedly promising better integrated graphics. My guess is that it will be 2014 with the Broadwell chipset.
I just wish they'd put a better display in the Air, period. I don't need four times the amount of pixels, but I'd really, really like a display with better contrast (Blacks should be BLACK, dammit!) and a wider viewing angle.
If Apple forces the display manufacturers to dramatically up their game due to Retina madness, the overall net result will be a win for all consumers, even Windows folks (though I think they'd rather cough up blood than admit that).
