For what it's worth, I do use an MBA (3,2) and I sometimes have problems with the glare screen indoors (have to move it around to diminish sunlight reflection).

Of course batteries add to the weight, I just mentioned it because sometimes you just need those extra hours, just like some people specifically need 8GB of RAM.

The disadvantage of a glossy screen is that at some angles, you'll get more glare. The advantage is that (as you note) if you modify its angle, you get less glare than you would with a matte surface.

Agreed that you sometimes need those extra hours. But to be fair you have to count their weight as well; you can double the usable life of a MacBook Air with an external battery if you need to but it also doubles the weight.
