We've known it's coming for a while - and with the "back to the Mac" news of late, it's been quite obvious Apple would tease the Apple lovers worldwide, today has arrived.

Apple have now shown off, and released all in a single day - enter, MacBook Air.

Available in 11 and 13" the new MacBook airs are thinner, lighter, and feature a massive number of upgrades and little things that always make the Apple products stand above the rest.

Apple have given the MacBook Air a breath of fresh air with the refresh - instant on, battery life is improved as well as standby times, solid state storage, all while being thinner and lighter. It's 0.68-inches at it's thickest, 0.11-inches at it's thinnest - weighing in at 2.9 pounds, to give some perspective, the old MacBook Air was 0.76-inches thick and weighed 3 pounds.

The screen sizes available are 11.6 and 13.3" - both running at 1440x900. SSD storage (available in 64, 128 and 256GB). 1.4GHz - 2.13GHz (slower for the 11.6-inch and going up faster with available upgrades in the 13.3" model). GeForce 320M graphics and 2GB of memory standard.

A nifty feature I thought I'd point out is something the MacBook Air does new - in case of a software emergency where the HDD needs to be wiped and OS re-installed, since the MacBook Air doesn't have an optical drive built in, it's even handier - it's a Software Reinstall USB drive for both models. The Software Reinstall USB drive includes around 8GB of data - consisting of OS X and iLife installers.
