Lenovo have launched a new ThinkPad X1 Carbon at CES 2014 which is the lightest 14 inch Ultrabook in the World, weighing just 2.8 pounds. The Ultrabook comes coupled with a 9 hour battery and optional built-in 4G capability to always keen you connected. Our favorite feature is the OneLink connection which does away with a multitude of connections and allows users to get power, Gigabit Ethernet, and dual display support through a single cable.
