Surface Book: Starting at 3.34 lbs (1,516 g) including keyboard Now let’s get a closer look at the technical specifications of the Surface Book, as this laptop is the ultimate powerhouse that will deliver amazing performance. You also will notice that there is a gap between the screen and the base, according to Microsoft, the design was built in purpose to offer the perfect balances for “lapability”. Similar to the Lenovo Yoga 3 Pro the Surface Book features a unique hinge design, which the company calls “dynamic fulcrum hinge”, which basically means that the hinge will look like it flexes as you open and close the screen. Even more interesting the Surface Book also converts into a tablet (clipboard), thanks to the “muscle wire lock” mechanism invented by Microsoft that releases the display from its base when an electrical charge is applied. The design of this 13.5-inch PixelSense display laptop is very sleek, as it shares a lot of characteristics found in the new Surface Pro 4 and previous Surface Pro 3 with a magnesium body, and unique vents to keep the system cool.
