Lenovo announces super-light Thinkpad X1 Carbon business ultrabook

Lenovo is bringing the ultrabook to the business world in a big way with the announcement of the slim ThinkPad X1 Carbon.

Lightweight, slim, and packing third-generation Intel processors and speedy solid-state drives (SSD), the four new ThinkPad configurations promise brisk performance and industrial-grade reliability.

An update to the 2011 ThinkPad X1 ultraportable, the new ThinkPad X1 Carbon is lighter and thinner, with third-generation Intel processing providing plenty of power for on-the-go productivity. Carbon fibre construction drops the weight to 1.36kg and the thickness to a mere 18mm (0.71in). Equipped with a 14in, high-resolution (1,600 x 900) display and Lenovo's Precision keyboard, the slim laptop looks and feels like a premium business laptop, and backs it up with a third-generation Intel processor, a 720p webcam for video conferencing, and mobile broadband available on most models.

While not the first ultrabook from Lenovo—the Lenovo IdeaPad U310, for example, is a highly rated ultrabook for the consumer market—it is the first to join the ranks of Lenovo's top business notebooks.

The ThinkPad X1 Carbon has four available configurations, offering a range of options in processors and pricing. The most affordable of the four is equipped with an Intel Core i5-3317U processor and 128GB SSD, and will retail for $1,399 (£890). The next configuration steps up to an Intel Core i5-3427U processor, and adds 3G mobile broadband for on-the-go connectivity, selling for $1,499 (£960). Bumping up to a 256GB SSD, with the same Intel Core i5-3427U processor and 3G mobile broadband, the next configuration sells for $1,649 (£1,050), while a faster Intel Core i7-3667U is available for $1,849 (£1,180).

All configurations of the X1 Carbon will feature a 14in, anti-glare display with a 1,600 x 900 resolution, with ports for USB 3.0, mini-DisplayPort, and Ethernet via USB dongle. Lenovo promises up to 6.3 hours of battery life from the sealed 45Wh battery, which is decent given the slim dimensions (0.74in x 13.1in x 8.9in) and featherweight construction.

The X1 Carbon will be released in the US on 21 August, though we're still waiting on details about an official UK release date and pricing.
