I turn on the device, the app in the upper left is selected and showing some content from that.
The device sits idle, I get drone footage of landscapes.
If I accidentally bump the wrong button on the remote and get sent into the Apple TV (streaming service) app, sure it advertises producte, but in general there are no ads.
In comparison, Google TV's homescreen is giant ads for content on services I don't subscribe to, Roku is at least as bad, Amazon is worse, and Samsung and LG......oof.
I enable app-only mode on my chromecast and does not see any ads.
I suppose my next device is an Apple TV or some kind of home brew Linux box.
The Shield at launch was an amazing product - premium UX and hardware, premium price point. Google changed the experience to an ad-loaded mess without providing an opt out for those who had spent hundreds of dollars on the Shield.
I was dogfooder, a huge advocate of the product, and someone who had convinced others to buy the Shield and Android TV devices. That UX revamp and how the team treated their customers (internal and external) turned me off the product for life. I tried the various competitors (XBox, Roku, Amazon) before landing on Apple TV. I now own two Apple TV devices - both of which are still getting updates many years after I bought them - and will continue using them for as long as the product line is maintained.
People in this thread have talked about Apple's clean beautiful ad-free UX, but the apps themselves are far better. Apple sets customer-friendly App Store requirements *and enforces them*. That means:
* The back button always works. It will bring you back to the home page of the app and then to the system launcher. It will not get stuck in an endless loop of "are you sure you want to quit?" and just dismissing that dialog like multiple Android apps do
* No loud obtrusive sounds on app startup (YouTube, Netflix)
* The apps are first-class priorities for developers. Circa 2019, the Paramount+ app was an inconsistent mess where subtitles were broken on some platforms. The Plex app wouldn't transcode certain formats on the XBox, and so on. None of these issues are a problem on Apple TV. Not every app is perfect (Dropout, I love your content, but your app is awful), but none of them are worse than on any competing platform.
Apple TV is a truly incredible product and ecosystem and one that feels like a joy to use. That's not the case for Android TV (now Google TV, I think?) even with a custom launcher.
It's more expensive than a 40€ Chromecast, but also SO MUCH BETTER.
I chose one over the Apple TV because I knew I wouldn't able to stand any limitations on sideloading. For a while I was running a custom build of Wholphin with patched libmpv/libplacebo to work around a bug before the fix was upstreamed. A device without the freedom to do that sort of thing would drive me nuts.
If you only care about file playback, bit still care about things like HDR and quality audio I would recommend something like the OSMC Vero V instead.
It's still relatively cheap, and open source, but also let's you playback something like a blu-ray rip without loss of quality.
It has the other bonus of not requiring any real setup or maintenance.
On most devices Dolby Vision, etc get downgraded or support only the streaming profiles (profile 5) . If you want full Atmos, Dolby Vision, etc you have to buy one of only a handful of devices. The Vero V is one of them. There are only a few others.
Mine comes with i5 8500t, 16gb ram and 256gb ssd, and it was like $150.
I've just used an old Intel NUC with Debian stable, a remote mini-keyboard and an automounted Samba share on the network forever. It's no more hacked together than any other computer. I do make the mouse pointer and the fonts real big. No apps required. Don't really need the keyboard except for mplayer hotkey presses - just the touchpad on it; if I need to do something that involves typing other than typing a password, I usually ssh in.
I think people are lowkey addicted to having shit sliding in and out and constantly being advertised to. How do you know what to watch unless somebody is constantly bombarding you with options? If it doesn't look like a star trek control panel, is it really TV?
If you like that, you can install Kodi. I haven't tried it since it was XBMC because I found the interfaces annoying and it had trouble dealing with networks, but I'm sure it's better.
> I've yet to hear of a reasonable recipe to isolate and secure such connected TVs
I don't even try. I overpay for dumb tvs in the present, or underpay for 10 year old tvs pre-Applefication. I've never owned a network capable television, or one with apps. I wouldn't.
edit: if your NAS is a separate box that can sit in proximity to your television, you could probably just run all of this stuff directly from the NAS. They spend most of their time doing nothing at all.
