Asus launches the Zenbook UX21 and UX31
 

It's been over four months since Asus first showed off its Ultrabook back at Computex, but the company has finally launched the UX21 and UX31 under the slightly odd Zenbook name. Presumably it has something to do with the low noise levels of Ultrabooks, but we're not sure it's the most memorable name Asus could've gone for.
