Surface Book is Microsoft's take on what the laptop should be

After gathering years of experience building Surface tablets, Microsoft has put its own spin on the traditional laptop with the Surface Book. This notebook blends an innovative-looking hinge with a high-quality screen, keyboard, and trackpad. The 13.5" display is built around the same ultra-thin PixelSense display stack as the Surface Pro 4's. Six million pixels serve as the canvas for Windows 10.
