HBO brought some of the content walls down when it opened up AirPlay support in the HBO Go app for iOS users, proving that it wasn't going to protect TV viewing at all cost. It just removed some more barriers: the premium channel has quietly rolled out an update to its Android app that enables HDMI video output. Provided a phone or tablet supports the connection (sorry, Nexus 7 owners), it too can pipe video to the big screen. The solution still doesn't let us watch HBO without a pricey TV subscription, but it will give us fewer qualms about catching up on Girls
