I genuinely like the Chromecast. It works with Netflix, Popcorn Time, BBC iPlayer, Twitch, YouTube, and I use an app called Airflow which lets me cast any video file. That's 100% of the TV my family watches. Plus it shows nice pictures in between all that.

I'm totally aware that it's basically just a fancy HDMI cable but we can easily cast from three operating systems, plus all our phones and tablets. I don't want a device any smarter than this, with menus and libraries of stuff it wants me to buy. The Chromecast model works great for us.
