The only glossy screens I've seen have been Dell, and they didn't impress me. Having said that, perhaps Apple really has done something different with theirs?
And FWIW, the 15" and 17" MBP screens would have looked like crap (with their viewing angles set so you pretty much have to view them head-on to see the colors correctly) if someone took a picture at the same angle as the one above where it's on the floor next to the guy's legs.
