If there was a matte option I would go for one for sure. But I 've got so dissilusioned with the glassy options apple has opted for across product lines that even a glossy with no glass on top seems like an oasis compared to what is currently available. I hate the glass on anything apple, I dislike it on the iphone, I find it a bit more annoying on an ipad, I despise it on a macbook and I absolutely freaking hate it on an imac. I am a happy camper with glass as you can see. 😀
Having said that it also depends on how good the screen really is, I will have to see it in person. For example the gen 1 mba had a gorgeous screen, only marginally glossy compared to other glossy screens from pc manufacturers, just enough to make the letters and colours clearer and not have that much reflection. Gen 2, or 1.B was worse, more glossy. So I 'd really like to see how the new screen looks, fingers crossed.
But I am so relieved we didn't get the dreaded glass on the air too, that I 've forgotten about matte.
