Chromecast is finally (FINALLY!) once again available for purchase from Amazon. (You can buy one here: http://phon.es/szcq) That's a big deal for a number of reasons, and we figured it'd be a great time for a deep-ish dive into Chromecast the dongle, and Chromecast the protocol. So Phil and Jerry tear it all apart. What is a Chromecast, why you would want one, and what its limitations are. (Note: we're cross-posting this in the Android Central feed. Thanks to them for that.)
