Apple today released the long awaited ultra-thin MacBook Air laptop. Steve Jobs used this years Macworld event to introduce the svelte 13.3″ laptop to the world. The computer is the world’s thinnest laptop. It’s tapering design is only .16″ thick in some places and .76″ at its thickest point. It is so thin that it can fit in an envelope! The machine features a standard 1.6 GHz Intel Core 2 Duo with 2 GB RAM, a 13.3″ LED widescreen display, magnetic latch, built-in iSight, MacBook-like keyboard with an ambient light sensor, multi-touch trackpad and 80 GB hard drive plus all the wireless connectivity you need for $1799.

The big selling point here is the ultra-thin design, but the multi-touch interface that allows you to manipulate object in much the same way as the iPhone but using the trackpad might be the most revolutionary for a laptop.This will undoubtedly spawn many imitations like the iPhone as touch computing is brought to the masses.
