It is definitely NOT bad enough to NOT get one. I recently switched from the 13 inch retina MBP to the 13 inch Air and the display is fine. You already understand that it is no retina but that being said, it isn't "bad" or "terrible."
Me using my wife's air over a weekend trip while I left my rmbp at home by mistake. Just love the wedge, weight and how cool it runs. I miss retina, but prefer everything else about the air.
I sold my rmbp and picked up an air. Made 300 in the process
Great to hear. Every once in a while I go to the Apple Store for some other reason and I look at the retina MBPs. The Air form factor would probably be worth non-retina to me.
My problem is I have Toyota Syndrome. God, I want to replace my MBP, but I see no good reason to do it. Soon enough, Apple will just stop supporting key OS features on it
