The Surface Book 2 15-inch is more than just a bigger version of its 13-inch sibling. It’s the most capable and performant Surface portable I’ve tested — and may be the best laptop ever.
It’s easy to dismiss the Surface Book 2 15-inch model as just a bigger version of the 13-inch. After all, it is physically bigger, heavier, and it sports a display that’s one and a half inches larger. But to do so misses the more significant point: the Surface Book 2 15-inch is a monster of a PC for raw performance and computational power.
