Like other tablets I've seen, the Surface 3 seems to also be missing a Kensington lock slot. Manufacturers know people want this on laptops, so almost every laptop has them including a $199 HP Stream 11.. Why would it be different on a tablet from $499 to $1900+? If the tablet is thick enough to fit a full sized USB port, it's thick enough to fit a smaller security lock slot. In what I find really a bizarre design, the docking station has a lock slot to secure the dock from theft, but there is no mechanism to secure the tablet to the dock. I would think a thief would be more likely to try to quietly snatch an unattended tablet out of the dock than to steal the dock itself. Pretty inconvenient to have to take the tablet everywhere you go. To the restroom? ??? The only solution I have seen consists of gluing a security cable on to the tablet. Tacky.
