Lenovo ThinkPad X1 Nano review: light it up Portability and performance, for a price Share this story If you’ve used a ThinkPad before, you probably know 90 percent of what to expect from the ThinkPad X1 Nano. All of the staples are here. It’s got the black carbon fiber chassis, the discrete buttons on top of the touchpad, the mechanical privacy shutter, the ThinkPad logo on the palm rest, and (of course) the red pointer nub in the middle of the keyboard. But one thing is unique about the X1 Nano: it’s the lightest ThinkPad Lenovo has ever made. Starting at just 1.99 pounds, the Nano isn’t technically the lightest laptop on the market. But it’s still one of the best combinations of portability, build quality, and performance that you can buy.
