I've been loving my mid-2012 15" rMBP (2.3 i7, 16GB, 512GB), but I'm not looking forward to the coming drop in price when Apple releases a refresh this fall. I try to sell my gear before the price drop happens, get a good deal on some older gear, and then upgrade to the latest several months later. Anyways, I'm currently being offered to trade my rMBP for $800 + a late 2011 15" MBP (2.4 i7, 16GB, 1TB Fusion Drive [256GB SSD + 750GB HDD]). This is the model with the ATI Radeon 6770M 1GB VRAM. It also comes the anti-glare high-res screen. I'll certainly miss the retina screen (though anti-glare will be nice) and thinner profile. And the battery life won't be nearly as good. But will there be any noticeable change in performance? This still seems to be a solid machine. Cosmetically it's got a couple light dings on the bottom, so that hurts its value, but its nothing that I can't live with.
