A couple of months ago we told you about a new Bluetooth controller from Power A called the MOGA. They said it would be available in time for the holidays and they delivered. They just announced that it will be in stores on October 21st for a price of $49.99. This is the first full featured controller to become available for mobile devices.
I'm in the market to purchase a bluetooth controller that will be compatible with the 7 and from my research these two controllers seem to be the most discussed options. I am rooted and do not plan on mounting it to the Nexus.
