To be fair, we all got along just fine wit low-res screens before the first Retina MBP.That is true. My point was that unit recently, we all got along just fine without it. And now that the 14" is live, many people here have convinced themselves that it is a new must have and maybe it is for a select few (for various reasons). If the screen was that important for the OP, he wouldn't have made the Air purchase today. Seems to me the OP is looking for assurance he didn't make a needles purchase.
Luckily the OP will have both computers to play with side-by-side and can decide which is more important, lightness or the screen quality and power.
