Don't know anything about newer Chromecast but I really love my older one. Its just a dumb stick with no apps built in that I can cast stuff from my phone to. The only recent annoying thing with it is that the YouTube app changed the behaviour when you're connected, so now instead of tapping on a video to bring up a menu asking whether to play it now or add it to the queue it now just defaults playing it now when you tap on it. Makes setting up a queue of videos really annoying now cause you have to tap on the three dots to add it to the queue now.
