What do you use your Chromecast for? Perhaps you stream content from YouTube to a non-smart TV, or use it as a mirror for your Android gaming. You might have a Plex server, and enjoy streaming video from your computer or server to your TV. Perhaps, like me, you get the feeling that even though an increasing number of apps are supporting Chromecast, the device could potentially do just a bit more, beyond its current raft of uses.
