Lenovo has unveiled a new laptop with a difference - it boasts not one, but two LCD screens.

Described as a mobile workstation, the W700ds has WUXGA 17-inch screen with 400 nits of brightness and a 10.6-inch secondary screen that can be tilted up to 30 degrees.

Due to be announced at CES 2009, but unleashed early due to leaks, the new ThinkPad will be offered with a choice of quad-core Intel Core 2 processors and Nvidia graphics. There's also the option of up to 8GB RAM, and up to 960GB of SSD/HDD storage.

A fair old lump of a laptop, the W700ds measures 16 inches by 12 inches, is 2.1 inches thick and weighs a whopping 11lbs.

"Why two screens? Most people are using two monitors at their desktop. So we wanted to give them all the things they are used to on their desk", a Lenovo marketing bod told Computer World.

The W700ds is expected to be available in January starting at $3,600 - around £2,435.
