Microsoft inadvertently confirmed in a user guide that it had a smaller Surface tablet ready to release when it unveiled the larger Surface Pro 3 last month.

Microsoft started selling some models of the Surface Pro 3 in retail today, and began delivering devices that customers had pre-ordered since the May 20 introduction.
