ASUS showed off a new generation of bamboo computers that are allegedly 100% recyclable. Full specifications can be read at Bit Tech.
You might think of bamboo as a novelty but there are some benefits, starting with touch: it feels lovely so that's one up over plastic, and it isn't cold or heavy as metal is. Not only that but it doesn't pickup finger and palm prints either. Asus claims it should still look as new even after significant use.
Asus also pointed out additional benefits in that the whole notebook is 100 per cent recyclable, and that after forming the bamboo parts first, 75 per cent less plastic is used in the injection moulding method of manufacture: 0.5mm of plastic to 1.5mm of bamboo.
The Ux3 of laptops are effectively the bamboo-made alternative to the Ux5 series and will be available in 13in, 14in and 15.6in sizes (models U33Jc, U43Jc and U53Jc respectively. At 31 - 34mm thick, they aren't 'ultra thin' ULs - although they do include an optical drive.
