I have three Roku TVs and two AppleTV 4Ks
Problems with the Roku.
- the hardware is severely underpowered and the interface is slow.
- you are the product. This fact comes from the CEO of Roku himself on an interview on Recode Media. He wants to make money selling user data and advertising. You can tell from half the home screen and rye screensaver being cluttered with ads and the remote with hard coded buttons that go to the highest bidder. I have one remote with a hard coded button with “CBS News”. Who would want that as a short cut? I have another one with a useless button to the defunct Rdio service.
- the remote doesn’t even have a way to do a 30s back/forward.
- you can stream from Windows devices but Google is moving away from supporting Miracast and of course you can’t stream from iOS devices.
They are big enough to make apple bow, other apps are not like that
There isn’t a requirement to make subscriptions only available in the store.
That does not stop Spotify from releasing an AppleTV app.
