Surface Book pro

When you've got a hybrid that's mostly laptop but with a removable screen, such as the Surface Book, there's usually plenty of room for ports and connections. When it's a hybrid that is primarily a tablet, your options suddenly narrow. The Surface Pro 4 fits in a single USB 3.0 port, a Mini DisplayPort for video, a microSD card slot, and an audio jack, which is essentially the same setup as last year's Surface Pro 3. By way of comparison, the Surface Book adds a second USB 3.0 port and has a full-size SD card slot.
