And I mean super slim. Announced at Macworld today, the MacBook Air is 0.76 inches at its thickest point, with Steve Jobs rejoicing in its ability to fit inside an envelope (rest assured, early adopters, that's not how Apple plans to ship the device to consumers).
It's got a 13.3-inch widescreen display, a built-in keyboard, and a multi-touch trackpad. It comes with an 80GB hard drive as standard, although there's a 64GB SSD drive option too. Intel slimmed down its Core 2 Duo processor for the device. You get Wi-Fi and Bluetooth, but only one USB 2.0 port. There's no optical drive built in, as you may have guessed.
2GB of memory will be the standard amount, and the MacBook Air will offer five hours of battery life. It costs £1,199 in the UK, and is pre-orderable immediately, with the first units expected to ship in a couple of weeks.
Apple also stressed its eco-friendly credentials, since it's the firm's first fully mercury and lead-free display, with less bulky packaging and a fully aluminium case.

Thicker than a ten year old Mitsubshi laptop.
About three millimetres thinner than superthins from Sony, Sharp and Toshiba but with half the features.
Is this progress? Is this something GOOD? Or are you just staring at the pinstripes again, while Jobs laughs his ass off as he counts his large stack of greens?
