Shawn Blanc, in a characteristically great review:
After using the 13-inch MacBook Air for almost two weeks, it has been difficult to pinpoint exactly what it is about this laptop that makes it so great. I don’t think it’s so much in what the Air is, but rather what it is not — or rather, what it doesn’t have. The Air doesn’t have an optical drive, it doesn’t have many ports, it doesn’t have a removable battery, and it doesn’t have much weight.
It’s the subtraction of all these things that adds up to make the Air such an attractive and incredible computer.
The MacBook Air will definitely be my next computer. My 2009 MacBook Pro is still going strong, but I can’t wait to see what the Airs look like in a couple years.
