i am considering the new Macbook Pro 13" and the Macbook Air 13". i read that the macbook air's had a kind of half-glossy/half-matte display. my real question is, what is the experience of trying to use either computer outside? i have an old macbook now (07) and an iPad and both are completely useless outside. are either of these even usable outside? i know the macbook 15" has an anti-glare option, but i don't want a laptop that big/heavy. obviously i'm not going to use it outside very often, but wouldn't like to be completely handicapped if the situation arises.
