Apple MacBook Air 13-inch (Thunderbolt)

Apple's new 13-inch MacBook Air (starting at $1,299, $1,599 as configured) is better than its predecessor in some key ways. Just like before, this ultraporable is wonderfully thin and light and wakes up instantly when you lift the lid, but the new Air ups the ante with a backlit keyboard and a faster Core i5 processor. The notebook is also more versatile, thanks to a new Thunderbolt port that allows you to connect the laptop to a growing number of super high-speed peripherals, including Apple's new Thunderbolt display.

While the 11-inch MacBook Air has a netbook-on-steroids vibe, the 13-inch Air truly feels like a full-grown laptop. It's just one that you can take anywhere--and look damn good doing it. The sturdy unibody aluminum construction, magnetic latch, and rounded corners make this machine just as elegant and futuristic-chic now as it was nine months ago.Because it now has a backlit keyboard, the 13-inch Air weighs just a little bit more than its predecessor (3 pounds vs. 2.9 pounds), but this is still among the lightest 13-inch notebooks available. Only the 2.6-pound Sony VAIO  weighs less. This laptop is still amazingly thin, too, measuring 0.11 inches to 0.68 inches at its thickest point.
