re: Best device for streaming movies/TV shows?

As a chrome cast owner I would recommend the fire stick or the latest Roku. I'm not particularly disappointed with the chromecast but one thing I didn't consider was that it basically hinders using your phone while it's running (apps that cast in the background seem to crash frequently at least on my phone) and i would prefer to have an option to use a remote and something with a stand alone OS.

Also, I have a smart tv and the chrome cast seems a bit redundant, except for allowing me to cast from the browser on my computer.
