I bought Chromecast in anticipation of the arrival of Netflix at the time. Coupled with a smartphone or tablet (iOS or Android), when an application is compatible is only happiness. I could test with Youtube, Canalplay, Netflix or to show my holiday photos stored on my Google+ to my guests. If you have an amp you can also listen to your music with the Google Play Music app. For this purpose I recommend here.
By cons to play in mirror mode the phone I recommend, there is a gap between the phone and TV, and the sound is choppy.
