The right edge of the Book's base houses a Mini DisplayPort socket and Microsoft's proprietary SurfaceConnect port.

As an added bonus, the 3.5 mm headphone jack lives on the display, rather than the base, for your on-the-go audio needs—although we're a little confused by its placement at the top of the Book.

On the left edge, we find two full-size USB 3.0 ports and an SD card reader.
