While the Surface Pro 4 is an iterative update to the Surface Pro 3, the Book is an entirely new machine. It’s a laptop but with tablet qualities, such as a large touch screen.
Apple hasn’t been wresting on its hardware laurels, however. The company introduced a brand new iPad Pro back in September and has recently updated both the MacBook Air and Pro with new internals, placing them at the front of the market.

So can Microsoft compete? Here is how the machines look side-by-side. (If you’re on a mobile device, click the image to zoom in.)
