We can't say we're surprised by this news, seeing as how Lenovo leaked it on its own site three weeks ago. Still, it's nice to get official confirmation, isn't it? Like we told you, Lenovo is releasing a touchscreen version of the ThinkPad X1 Carbon Ultrabook, appropriately called the X1 Carbon Touch. And, as expected, it's on sale this month. Today, actually, starting at $1,399 -- a $150 premium over the non-touch model. Like the regular X1 Carbon, it has a 14-inch, 1,600 x 900 screen, a carbon fiber chassis, an Ivy Bridge chipset, built-in 3G and a backlit ThinkPad keyboard, complete with that signature red pointing stick.

The main difference is that the touchscreen makes this a bit thicker and heavier (20.8mm and "less than" 3.5 pounds, versus three pounds and 18mm thick for the non-touch model). Even then, 3.4 pounds is still lighter than some 13-inch Ultrabooks we've seen. In fact, Lenovo is billing it as the world's lightest 14-inch Ultrabook, though we all know how short-lived such distinctions are. As for battery life, Lenovo rates this for 8.2 hours of runtime. If true, that would be very good news indeed, given that we've yet to test a touchscreen Ultrabook with decent battery life.
