Microsoft calls it the tablet that can replace your laptop. The Surface Pro 3, which was announced in May and started shipping in June, comes with a 12-inch touchscreen, a 3:2 aspect ratio and 2160x1440 resolution display, making it a healthy size for note-taking and showing presentations. It comes with a choice of Intel i3, i5 or i7 chips so there’s plenty of processing power, and it supports any apps that run on Windows 7 as well as apps designed just for Windows 8.1. Equipped with a super-thin and light keyboard/cover it seems more like a laptop. Docked with external monitor, keyboard and mouse, it makes a good desktop replacement. Here’s a closer look at the Surface Pro 3.
