Nothing here on a 2012 MBP 13" retina with a 10/02 manufacture. In my opinion, based on this sample of one, the best display I've owned. The colors are gorgeous, it's bright and "rugged".
When the screen gets dirty enough I wet a terry towel that I use on my cars (washed, of course) with whatever cleaner my wife has under the sink. Usually Simple Green or that organic Arm & Hammer stuff. There is not one single mark on the screen. I don't do it often though, maybe twice a month.
I know what the OP is talking about. At least I've seen them in pictures. As pointed out it's most likely the AR coating. Maybe some batches had the coating incorrectly applied.
I usually just lick my finger to wet the spot and then wipe with the apple clothe. If my nasty mouth isn't enough to wear the screen, I think I'm good.
