That Asus was set to launch a bamboo-clad laptop was no secret; it's been demonstrating its 'EcoBook' laptop for the past year.

Today, however, the Asus Bamboo, as the laptop has been renamed, got its official unveiling at the Stuff Live show at London's ExCel exhibition venue.

Bamboo was chosen as a suitable casing for the laptop since it's a plant that grows very fast and therefore seen as relatively 'green' since deforestation is not an issue. Bamboo also has a high degree of tensile strength, is lightweight and flexible yet strong enough to withstand knocks.

The Asus Bamboo range of laptops kicks off with an 11.1in model and a 12.1in model. Both run Windows Vista and have a low energy-consumption LED-backlit display.

Greenies, however, will pay a fair amount for the 'environmentally sensitive' design of the Asus U6 Bamboo. The 12.1in model has a suggested retail price of £1,349. For this you get an Intel Core 2 Duo T9400 processor running at 2.4GHz and 4GB of RAM. The U6 Bamboo will come with a 320GB hard disk, a DVD writer and an integrated webcam plus a multi-format card reader.
