David Pierce, writing for Wired: As Microsoft went to create the Surface Book 2, the company once again tried to bust categories. The result is the most combinatory device Microsoft's made yet. It's a laptop (screens measure 13 or 15 inches; there's a keyboard and trackpad) -- and it's also a tablet (the screen detaches, you can use a pen, everything's touch-friendly), and it's also a desktop. A stupendously powerful one, at that: It runs on Intel's new eighth-generation quad-core processors, in either a Core i5 or Core i7 version. The higher-end models come with Nvidia's GeForce discrete graphics, up to 16 gigs of RAM, and as much as 1 terabyte of solid storage. All that in a fanless body that gets up to 17 hours of battery life, and weighs about 3.5 pounds for the smaller model or 4.2 pounds for the larger. What does all that mean? Microsoft claims the smaller model is three times more powerful than the last Surface Book, and the 15-inch runs five times as fast. Those are meaningless comparisons, but the point holds. This thing screams. More useful are the comparisons to Apple's latest MacBook Pros: Microsoft claims up to 70 percent more battery life, and double the performance of Apple's laptops.
