MB Air doesn't have a matte screen. It was always glossy, back to the first model. Glossy started with the original polycarbonate case MacBooks. Matte was a BTO option, free I think, on the (roughly) concurrent generation of MB Pros. It may have eventually been made a BTO option on the polycarb MacBooks -- I don't know because I wasn't in the market and I had a MacBook bought at retail w/ a stock glossy screen.
At any rate, the Airs were all always glossy screened, and I don't think there was even a BTO matte option; not for the first generation, perhaps the second. Glossy screen troubles me not a bit. But I wanted to upgraded -- side-grade? -- my 13-inch Air to an 11-inch Air, but having discovered about a week ago what they left out, I won't do it either until the backlit keyboard is at least a BTO option.
Maybe the new MB Pros will be more Air-like in size/weight, w/ a backlit keyboard. Otherwise I'll go back to something similar to the current 13-inch MB Pro before I'll give up the backlit keyboard. I can barely even type on an unlit keyboard anymore. Although at this point I could probably just slap an iMac on my desk and use my iPad w/ my keyboard dock and/or Apple wireless keyboard as a portable. I'm a writer, not a film editor.
But it's weird because a bunch of Windows PC laptop manufacturers jumped on the backlit keyboard bandwagon after Apple started using them. Now Apple drops it in a fairly premium model. Go figure.
