Ahead of CES, Lenovo is refreshing its flagship X1 laptop lineup. The company last updated the ThinkPad X1 Carbon and X1 Yoga this past August, so there aren't any drastic redesigns this time around. Like the previous generation models, the updated laptops feature Intel's latest 10th-generation "Ice Lake" processors and up to 16GB of RAM. One new addition is that you can now configure both laptops with as much as 2TB of internal storage, up from the 1TB max in last year's models. Lenovo has also tweaked their keyboards to add function keys that allow you to quickly start and end a voice-over-IP call.
