Microsoft always tends to do better the third (or, in some cases, tenth) time around, and the Surface Book 2 -- the third iteration of the product -- is no exception. It's a three-in-one portable with a lot of power under the hood and plenty of advanced features.

Wait, three-in-one? If a laptop with a 360-degree hinged display qualifies as a two-in-one, then a laptop that also has a detachable display must score a third point, right? The Surface Book 2 can flip around for view-mode tasks (such as presentations and movie-watching), or it can separate for full-on tablet duty.
