Asus has finally pulled the curtains back on its ultrabooks which will now be called 'Zenbooks'. Initially unveiled at Computex, the new range of devices includestwo models, the 11.6-inch UX21 and the 13.3-inch UX31, both of which mirror Apple's Macbook Air range.

They also come with Bang and Olufsen's ICEpower speakers combined with the company's SonicMaster technology.

The Zenbook UX21 and the UX31 will go on sale from today and will cost £899 and £999 respectively. A couple of days ago, Acer also announced its own Ultrabook, the Acer Aspire S3 which will cost $899 and will come with a 20GB SSD drive and a 320GB hard disk drive.
