Microsoft’s Surface Book Gets Faster Guts, a Bigger Battery

A new Surface Book is headed to retail shelves. It looks just like the original model from last year, but it has an updated processor and a whole lot more battery life.

According to Panos Panay, who runs Microsoft’s Surface division, improving the Surface Book was no easy task. People already love the debut model, with its detachable 13.5-inch screen, 12-hour battery, and chippy performance. In fact, Panay says the Surface Book has a higher level of customer satisfaction than any other portable PC in the Windows universe, and even the MacBook.
