The obvious question: Why would you buy this if you already had an Apple TV (or were considering buying one)?<p>* Cross-platform support, not just iDevices<p>* For apps that integrate with the SDK (currently Youtube & Netflix, but I am sure more will be coming soon), the processing of the content can be transferred to the the Chromecast. Hence, once you "flick" your Netflix content to Chromecast, your phone is free and not processing content anymore unlike Airplay, which is a huge win for your phone's battery.<p>* All your phones/tablets/computers become your remote/controllers.<p>* The price (at $35, it's a relatively low-risk impulse buy)<p>* UPDATE: It automatically switches to the HDMI input channel when streamed, atleast on my LG TV. My 3rd gen Apple TV doesn't so I have to find the TV remote to switch HDMI inputs, which can sometimes be annoying.
