HotHardware posted a review on the Lenovo ThinkPad X1 Carbon Ultrabook

Ultrabooks continue to be the hot trend in the Windows notebook arena. With the recent introduction of Intel's new, low power 3rd generation Ivy Bridge Core series processors, designs are becoming thinner with every iteration, while paradoxically it seems, performance continues to scale higher. We've seen Ultrabook machines from virtually all the majors here at HotHardware and many of them are targeted at consumers on the go where thin is in, and not so much the business user, where practical usability, durability and performance are critical. Lenovo however, is stepping outside the box with the latest addition to their ThinkPad lineup for road warriors and cubical commandos alike.

The venerable Lenovo ThinkPad, with its little red TrackPoint nub has gone the way of the Ultrabook. If there's one small dig ThinkPads have taken with regularity over the years, it's that though there's a ton of quality and substance built into these machines, style was not a hallmark of the brand. The all new ThinkPad X1 Carbon could very well change the utilitarian stereotype of the Lenovo's business-backed line-up, however. It's very well-made like a ThinkPad should be but it's thin, sleek and dare we say sexy? Go-on little ThinkPad, back that a... oh never mind. Let's run down the specs and stick with the program.
