Lenovo has updated the ThinkPad X1 Carbon with Windows 8 and a touchscreen and called the new model the ThinkPad X1 Carbon Touch - catchy, we know.

Just like the original 14-inch X1 Carbon, the new model sports the same carbon fibre chassis, weighs 1.5kg and measures 20.8mm thick.

From what we can tell, the new touchscreen adds a little bit of weight and thickness to the proceedings, but not enough that you would really notice, unless you are the kind of person that notices 2mm.

“Bringing touch gesture control to our best ThinkPad ever is a natural evolution of the portfolio and a big step towards fulfilling our promise to bring computers into a new PC+ era,” said Peter Hortensius, president, Lenovo Product Group. “We are excited to be able to offer customers the best experience in a thin and light business class Ultrabook. The X1 Carbon Touch is the Ultrabook to beat.” 

The new touchscreen display supports 10-finger touch, while those not keen on getting their screen all smudged can opt for the large, multi-gesture glass touchpad instead.

A new optional slim 65W AC adapter is now offered as well, allowing you to shed even more weight, but it still weighs more than the laptop itself.

The Intel Core i5 version of the ThinkPad X1 Carbon Touch will be available in the UK from January 2013 with a list price of £1,800. US readers can get it from today starting at $1,399, a $150 premium over the now regular non-touch model.
