Dan Frakes’s detailed review of the updated MacBook Air. Short version: they’re faster, better and cheaper than last year’s model.
I’m going to be purchasing a new MacBook some time within the next year, and I’ve gone back and forth between the 11-inch and 13-inch MacBook Air. The 11-inch is beautifully small and functional, but I’m concerned that using Xcode and the iOS Simulator on it full-time would be masochistic.
