My experience with Apple is that it doesn't play nice with other ecosystems. Cludgy workarounds are usually possible but if you are doing that you may as well go for Linux.

I use the pro in comparison because the non-pro version is even more dated on lesser hardware and going to be sluggish, lesser in capabilities than other alternatives in the android space.

For one it can't (reliably) run a plex server or other services so there's really no advantage other than brand loyalty to NVIDIA to buy the non-pro shield over say a Walmart Onn 4k for half that price. (And that's the truth, you can't reliably run other services on the non-pro shield without incurring a noticeable performance penalty and degradation if it's even possible in the first place)

I compare apples to apples here or tried to be honest. ATV4K has 4GB RAM, Shield Pro has 3, there are various other reasons to compare them, they're both the top of the line. Though as I mentioned if you want to compare the non-pro shield then there's the smaller ATV4k which still has without buying an SD card 64GB of storage for $129.

As to "offers". I used retail prices you use this which I consider dishonest and desperate. Not a credit to your side. Apple TVs regularly go on sale multiple times a year via official dealers like Amazon, Target, Costco. Shield's rarely go on sale, if you're talking about used or shady third party dealers then you're not doing an honest apples to apples comparison.

Shield promoters are strange people to me in 2024. I don't think you've taken a proper inventory of the landscape. People call apple users shills and so some of them are, but I see shills for various brands and people unfortunately taken in by them.

Yes it was revolutionary when it came out, now it's not. That's life when a company decides to abandon a product line for all intents and purposes and yes no hardware updates, not even a revision in 5 years signals stagnation. They don't need a major processor upgrade but not bumping a few minor aspects of the hardware like the HDMI ports version or the WiFi for instance just shows they don't consider it an important part of their brand and I'm not sure why you'd buy into something that could be sunsetted without any surprise come January.

And not dropping the price which is rather hefty and high considering costs should have gone down over time is also a not so nice sign of greed and inattention. Apple dropped their prices. No reason NVIDIA with its scale and buying power doesn't have the ability to drop the price if they're not going to at least actively develop it to justify it.

VLC is awful for network playback. It's fine for local fines (though mpv is better) but playing network files you're going to have pixelation, stuttering, all kinds of problems I can say from experience trying it on both wired and wireless connections. I strongly recommend Kodi, Plex, Emby, Jellyfin, etc over VLC for non-local playback that's smoother and better.

Ad-free youtube is likely soon to go the way of the dodo given the aggressive moves by youtube to stop it and most people don't need or want that on their TV because they're interested in paid or FAST streaming services. You have eclectic tastes and needs and that's fine but recommending that to your average person isn't doing them a service. And it's nice to think of others, not your own biases and unusual needs.

And most people don't need an FTP server (an FTP server, serving what exactly given you're talking about the non-pro and SD cards, that's not a great experience compared to an ext hard drive, if you're going to do that, go for the pro and connect an external spinning disk HDD or SSD via USB).

Most people don't need a torrent client (and again on the non-pro you're talking about downloading onto an SD card, major yikes don't do that, again if you want to do that please recommend people the pro for USB drives and use that in your honest comparisons here).

Both the above also require investing in an SD card (or an external drive via USB for the pro which is the better way to go). Reliable non-trash (good brand, good speed) SD cards are going to drive up that cost you stated another $15+ dollars which puts even your non-pro "on sale" (good luck finding it) shield within $5 spitting distance of the ATV4K higher end 128GB model (to get that much storage on the non-pro shield via SD card of a decent brand and speed would absolutely put your costs in line with the ATV4k 128GB model).

You mention alternative launchers, most people don't want to do that. Apple TV is ad free out of the box without mucking about with ADB and other things. Again consider the average user and how they're not going to do that.
