Back in October, Microsoft surprised everyone by announcing the Surface Book 2. In fact, it was the first Surface product to be announced via a press release, rather than at an event. But in addition, it's probably the most exciting Surface of the year.

After all, the Surface Laptop is, well, a laptop, and the new Surface Pro is an iteration on previous models. The Surface Book 2 came with a new 15-inch model in tow, along with a more powerful CPU and GPU. The old sixth-gen 'Skylake' chips were replaced with the quad-core, eighth-generation 'Kaby Lake R' processors. And along with the additional CPU power, the old mobile GPUs in the original Book were replaced by an Nvidia GeForce GTX 1050, and a GTX 1060 for the 15-inch model.
