What you see above is actually the official Nexus 7 pogo pin dock, where it was first revealed and made available to the masses this year, but for one strange reason or another, it seems that the Nexus 7 dock is no longer available on the US Play Store earlier this afternoon. It seemed rather strange, especially when you consider how this $30 accessory has been a long time in coming for many of the loyal Nexus 7 owners out there after having gone on sale earlier this March.
