I bought the darned dongle in 2019. It's not that old. But all it shows when idle is a screensaver like thing with rather nice photos, the weather and the time. Much like an over-sized Google Nest Hub. Only way that I know of to play say Netflix on it is to have the Netflix app on my phone, and hit the screen cast icon up top. That and other services requires multiple redundant apps on the phone, taking up phone space, just to cast video to the device. Very impractical. The only other way is to use the Assistant on a Nest Hub, but they still haven't fixed the bug where it starts each series from season 1, episode one, even if I was still on season 6 or so.
Also doesn't work with any content from the Apple TV app, since, well, there ain't none for Android, and the iOS version doesn't seem compatible. Since I'm trying hard to avoid buying anything new anymore aside food and necessities, the idea of buying yet another in a long line of Google's disappointing items goes right against that.
Your link goes to where you can buy a smart TV with Google's service built in. Pretty much Google TV, and I've been down that road before. Their older Google TV Service ended up forgotten garbage much like anything else they do. Stuck on Android 3.0 Honeycomb and all apps eventually ceasing to work on it. Thing had major wifi issues too. I already got perfectly good TVs that I have zero intention of replacing.
As for buying a Gen 1 Apple TV, that thing didn't even support apps or the internet much. It was kinda like a Zune, only good for playing local network media at best, with the wifi being gimped just like one on a Zune. No access whatsoever to say, Netflix or Hulu or Amazon.
A Gen 2 didn't even have the app store and that was the first ATV I ever bought, and promptly returned since it had less app support built in than the Google TV above.
I hate how many updates Apple gives out, making peace of mind of never worrying about another UI change never happen. Although cutting support for Android 3.0 and then gimping just about every app built into the Google TV I once had was bad, at least while the wifi worked, Netflix and Prime still worked. But I do wish Apple would just respect my choice and leave me alone. I mean they put a 'don't update automatically' button in there, why not just leave me alone?
