The X Series of Lenovo's ThinkPad laptops puts portability first, pairing smaller screen sizes with competent components. The ThinkPad X270 is a business laptop with a 12.5-inch screen, all the ports you could need, and a surprising amount of computing power. This configuration will cost you, but it's speedy, and offers a hot swap battery system that adds up to impressively long times off the charger. It's not especially slim for a portability-focused laptop, though, and not every business or user can justify the price of the top-end configuration of our test unit. As such, Lenovo's own ThinkPad X1 Carbon remains our top pick for business laptops, delivering similar performance and a truly ultraportable feel for less money.

Stout Package
As a travel-friendly laptop, the X270 has a compact build, measuring 0.8 by 12.03 by 8.21 inches (HWD) and weighing 3.07 pounds. That's small enough to slip into almost any bag or laptop case, though its weight doesn't do much to differentiate it from the 3.1-pound Lenovo ThinkPad T470s, which has a 14-inch display. It is still thinner and smaller than the T470s, so it takes up less space, but it's hard to say it feels like a true ultraportable given the density.
