I generally agree, but I'd make a few points. 1. the 4K fire stick is much faster than the older ones, so you might want a 4K stick just to enjoy the higher performance even if you don't own a 4K TV 2. The lifecycle of a five hundred dollar TV is longer than that of a streaming device. It may be that the 4K FTV stick provides a better app experience than a 4K TV that's a few years old. 3. The app selection on many 4K TVs varies. People who want support for say Disney+ or some of the network TV apps or less popular apps may not get them on their 4K TVs. 4. With the FTV particularly, many people like the open-ended android platform that lets them sideload apps and customize and whatnot. I have a lower-end Vizio 4K TV in my bedroom. The netflix and amazon experiences are good-certainly better than my Tivo mini, but there are many things it doesn't support. It's fine for my bedroom. But if I had the same TV in my living room, I'd spend 30 bucks and add a 4K firestick to it.
