Lenovo has officially unveiled the much-anticipated ThinkPad X300 notebook PC, designed for today's most demanding "road warriors" with the asterisked claim of being the thinnest and lightest full-function notebook in its class.

Asterisk = "Compared to major vendors offering 13-inch widescreen notebook PCs: Sony, Dell, Apple, Asus and Fujitus Siemens. Full featured defined as including technologies such as built-in DVD burner, selection of USB ports, Ethernet connection, replaceable battery and more". Dig at Apple wethinks.

The ultra-thin, ultraportable has a 13.3-inch WXGA+ display, measures less than 1.85cm at its thinnest point and has a starting weight of 1.33kg.

The ThinkPad X300 combines a "number of leading technologies" such as solid-state drive storage, a LED backlit display, ultra-long battery life (up to 10 hours) and enhanced wireless connectivity.

Depending on what model users opt for, the ThinkPad X300 can offer an optional built-in 7mm DVD burner. It also includes stereo speakers, digital microphone and an integrated camera.

It offers "roll-cage" durability, integrated fingerprint reader, and comes equipped with a 1.8-inch 64GB SSD that provides more than twice the performance of a regular 2.5-inch hard drive - and with no moving parts - four times greater shock resistance than hard disk drives.

The notebook also comes with the latest Intel Core 2 Duo processor technology, up to 4GB memory and Lenovo's ThinkVantage Technologies.

Available immediately, the ThinkPad X300 notebook price starts from £1700.
