Chromecast is pretty great, but as it is merely an extension on the pc/mac within chrome all you can do is view a single tab of the browser, or use one of the services. I'm not concerned with broadcasting my entire desktop or laptop environment to my tbs, I just want access to all of my tvs, movies and music in he. With plex media server and plex apps, I now have easy, user friendly access to all my media on my tvs or other devices (cell, tablet, and my roommates can access my media content on their devices as well).
