If you're looking to get your hands on the elusive official dock for the Nexus 7, it's now finally listed in Google Play for $29.99. Google has thus far set a limit of two per person.
The dock, which charges the tablet via the pogo pins as well as serves as an audio output via a 3.5mm jack, runs $29.99. You can read our complete review of it here.
Google's currently listing it with a 1- to 2-week shipping time, which generally means there's a better than average chance you'll actually get it sooner than that. (We're currently seeing an anticipated shipping date of March 17, which doesn't make a whole lot of sense, being a Sunday and all.)
