It's that latter functionality that a startup called Green Throttle wants to tap into. Given the horsepower of today's smartphones is makes a lot of sense. The company envisions harnessing the power of today's well-equipped Android smartphones and tablets in order to play console-like games on your HDTV. Right now the concept is limited to select devices — Google Nexus, Samsung Galaxy S II and S III, HTC One X, Kindle Fire HD, and Asus Transformer — though the company says it's adding to the list quickly. The system is fairly simple. You load Green Throttle's Arena app on your compatible device and start gaming using the company's Bluetooth-enabled Atlas controller, which looks a lot like an Xbox 360 controller, then push your phones HDMI output to an HDTV."
