@gsuberland respectfully, I don't understand this perspective. The "attached computers" aren't that expensive (a Fire TV Stick is ~$30), and it's always seemed beneficial to me to decouple "high-quality display" from "streaming source" so that you can upgrade or swap them out independently.
Even if truly-good ad-free Smart TVs existed, I'd still prefer a high-quality dumb TV coupled with a hackable actual-computer.
