Personally I think there's possibly an intersection of people who want a "dumb" tv and people who would do something similar to this, I for example, would love to have a "dumb" tv and just hook up one of those firestick/chromecast/other-product dongles into one of the available HDMI ports.

I really see no point in having an integrated computer in my TV that's just gonna be stop being supported a couple of years down the road, might as well have that part be detachable for when it becomes obsolete, I'd just buy a new one, the display would still be good.

I do this with a PC monitor and some powered bookshelf speakers. Works pretty well since I live in a tiny place and have no room for a TV and PC setup. You can even get 40" ones these days. They do lack some TV features like I wish it had an optical out. Mine has a headphone out but the DAC makes everything sound like turds. A cheap HDMI switch solved that issue though.

I'm clinging to a cheap PoS TV that has bad pixels and a blurry smear in the panel, just because it's big, not-smart, and only 1080p. I don't need 4k, although I have nothing against it per se, and I like the fact it usually means better FPS in games. But I don't want a bunch of "smart" stuff constantly getting in the way of what I want my tv to do, which is show the pictures being piped in by devices I actually trust.

I used my CRT for long time as smart TV. First Gen Roku had analog outputs. :)

You know that moment when TV started getting too smart that it displayed ads when changing volume, or whatnot. Or even connect itself to open WiFi network.
