Lenovo’s ThinkPad X Series is one of the company’s most popular product categories. People are getting more and more into portability and mobile computing. Thin and light is the name of the game and the industry has recently seen a huge surge in demand for ultrabooks.

The ThinkPad X1 Carbon has been out for about a year and it has proven to be an excellent product, garnering favorable reviews from both critics and users. Now shoppers have the option of considering the ThinkPad X1 Carbon Touch.

If you’re looking for the major difference between the X1 Carbon and the X1 Carbon Touch, the answer is going to be obvious. With the installation of Windows 8, you knew Lenovo would eventually go with a touch display version of the X1 Carbon, and that’s what you’ll find.

The two devices are so similar you’d be hard-pressed to tell them apart without a set of calipers. Fortunately, I have a set of calipers (and some other tools) and can confirm that the Touch is a shade thicker (2mm), a hair heavier (3.1 versus 3.0 pounds), and about 15 percent dimmer than its forebear — all signs of the price to be paid for adding a touchscreen to a laptop. That said, according to Lenovo, it is still the world’s lightest 14-inch notebook with touch.
