What&#x27;s cool about it? The ability to send any kind of video to your TV with very little fuss. That has historically been a pretty tricky thing to do.<p>Is that revolutionary? I&#x27;d argue no. It&#x27;s effectively a virtual HDMI cable between your phone and your TV - more convenient, but not revolutionary.<p>I&#x27;ve long since ditched my Chromecast for a Roku, which is far easier to use in a shared environment, and (IMO, of course) having a remote is infinitely preferable to having to use my phone. That said, Chromecast comes with a bunch of interesting JS APIs that could be used to make something interesting. I just haven&#x27;t seen anyone do it yet.
