What kind of response is this?
Care to elaborate? All smart tv's have built in apps. Usually they suck, are slow, clunky and nobody uses them. Hence why we use ATV.
Listen, I've been an Apple TV fan since Day 1, had the very first Apple TV on the day it was released and all the versions thereafter. I get the love for the product. I do.
But years go by and the lead Apple had in UI speed and ease of use has evaporated as others have stepped up, especially those bundled in our TV's. Hate to say it, but the Android TV in my new Sony XBR is only a hair slower than Apple TV and the convenience of it being built-in can't be overstated, it's just far easier and seamless an experience.
And besides the UI, Apple offers nothing. In the end, it's about getting to Netflix, Prime, and YouTube quickly and the Android TV in my Sony does it faster. And the apps are the same across platforms, there is no difference in how they function right down to click patterns and voice commands. And while I loved the ATV touch remote when it first came out, I now prefer the typical d-pad style remote of the Sony, it's just more precise.
My Sony TV is brand new. Not sure about the age of your Smart TV but the gap has closed to the point where Apple TV is practically unnecessary. In fact I only use it now as a twice-a-week accessory to stream my iPhone home videos and connect to my HomePod. It's shame, really. The only way Apple can compete in this space now is to make their own 4K panels with Apple TV built in for a completely integrated experience. Otherwise I won't be buying another one.
