Here is the spec page for the new Macbook Air, the new heir to the Macbook and all that is cool about Apple design, ergonomics, and lightness.
Specifically, I was concentrating on two things. Memory and battery life. For either the 11" or the 13" model, the maximum of allowable memory is still at 4 GB while the battery life remains the same - 5 hours for the 11" and 7 hours for the 13".
Until one or both of those specs improve, I think my refub late-2010 Macbook Air from last year stands out pretty well.
I know that the processor has been given a great upgrade. For someone who uses his MBA, to hack out writing, I won't be too jealous of proud owners of these 2011 Macbook Airs. Well, maybe just a bit.
