The new MacBook Air, or AirBook, was presented minutes ago at Macworld Conference & Expo in San Francisco, CA. This piece of machinery will set you back $1799 for the standard version. The very much optimized will set you back another $1299.

MacBook Air is nearly as thin as your index finger. Practically every detail that could be streamlined has been. Yet it still has a 13.3-inch widescreen LED display, full-size keyboard, and large multi-touch trackpad.
