Microsoft Surface Book 2
It's not the lightest laptop on the market — the 15-inch model weighs over four pounds — but it is among the fastest. Packing 8th-generation Intel dual- and quad-core processors and Nvidia GeForce graphics, the Microsoft Surface Book 2 has the computing power to crunch through any job (or game) with ease. It retains the detachable display of its predecessor, letting it convert from laptop to tablet instantly, and its 17 hours of maximum battery life ensure it'll run all day without needing a charge.
