I own an older model version of it from a few years back, combined with a Google TV Chromecast.
Yes, it's more expensive than a midrange TV, but it also lasts me a lot longer and isn't stuffed with ads. If I'm ever sick of Google TV I can try to jailbreak/root it, without the risk of bricking the entire TV, or just replace it.
Be careful with commercial displays. Some are just designed to show static ads or pictures, which means they have a very slow response time or low resolution.
I don't know, I'd be fine with a 55 inch 4k ViewSonic display for under $600. The 65 was $850 and $1200 for 75 inches. That seems relatively normal, right?
That's the idea but being honest there aren't many nice streaming box.
Like there is Roku and the Xiaomi one?
What else? Fire TV?
Chromecast I do not count because you need to cast to it.
That's true, but I considered it an investment for longer term instead of buying a cheaper midrange TV. With the exception of lacking HDMI 2.1, my 55" monitor has all the modern features, with the bonus of having dual input modes and a displayport.
It's basically what "dumb" TV's used to be, minus the antenna, but that's fine as a cord cutter.
