The Surface Book 2 is the most combinatory device Microsoft’s made yet. It’s a laptop, with a keyboard and a trackpad. It’s also a tablet (the screen detaches, you can use a pen, everything’s touch-friendly), and a stupendously powerful desktop. The machine 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. Power don’t come cheap, though. The Surface Book 2 starts at a whopping $1,499. Read the review here.
