Announced in October of 2015, the Surface Book sports a 13.5-inch PixelSense screen with a “dynamic fulcrum hinge” that provides a smooth, solid feel to the machine. The screen has the highest PPI of any comparable machine, at 267PPI (3000 by 2000 resolution).
The Surface Book weighs 1.6 pounds, and like all Surface machines, it is milled out of magnesium. In fact, the Surface Book maintains the general design philosophy as the rest of the Surface devices, down to the typical venting along the edges of the screen. The machine sports two full-size USB 3.0 ports, a full-size SD card reader, mini-DisplayPort, and a Surface Connect port.
The Surface Book also houses its processor in the display, which doubles as a tablet. Meanwhile, the keyboard houses the discrete GPU (if the model you select has it) as well as the added battery for longer use. There’s also a facial recognition camera, providing built-in Windows Hello support, and an 8-megapixel camera on the back with autofocus and 1080P HD video support.
