Antiglare on glass is possible, but I'd be willing to bet that's not the option here. I am fairly sure it has no glass, as the aluminum bezel is indicating.
Anti-glare on glass is an optical coating like that used in camera lenses. It has been used in high-end CRT computer monitors for at least 25 years. I remember seeing this in some color IBM terminals at school. The resulting image quality is very high, but they smudge VERY easily and visibly, since any fingerprint oils change the diffraction characteristics of the coatings. A matte LCD does not smudge nearly as easily.
Structurally, I'm sure the regular, glass option is more rigid. I don't know if there are any long-term implications. The old MacBook Pro design did start to bend visbly with rough use. Some people have machines where there is a visible gap between the lower bezel and the screen. I never had this problem with my MBP, but I always treated it very gently and I especially avoided pushing the screen beyond its maximum angle.
The Air is definitely more rigid than the old Pro, but the bezel is quite wide so that might be part of it. Still, the hinge design for the Air and the new MacBooks is different from the old Pro's. There is no plastic between the hinge and the top shell; there is metal to metal contact at at least two points on each hinge. The shell itself appears to be more rigid.
My best guess is that the deglossed 17" MBP is stronger than the previous 17" MBP, but not quite as strong as the glossy version. Those who have any doubts should best wait till they can actually see one in person.
