I'm actually up to 6 chromecasts now, I have one for every TV in the house but one. Kids want to watch a show on netflix, pull out the phone and turn on a movie in one of their rooms. I have Plex and Showbox for lots or other movies and shows. I even have a chromecast on my smart tv because it works better than the apps on the TV. I'm all in on these little things. They still have some improvement to do with the browser casting but the app support is really nice at this point.
