You can have Ubuntu laptop, Android phone, WebOS TV. They all support Spotify and Netflix, you can cast videos from Android phone to your LG TV.
The problem with going that route is that you have to be involved in creating and maintaining a great user experience. I love ubuntu, but it's not without it's quirks that require a certain amount of troubleshooting to overcome.
4 years ago, I was all in- Mac, iPad, iPhone. In the last 4 years, I've been driven away by Apple seeming contempt for professional users.
Their contempt for other competition is even graver cause for concern.
