> You should update the TV when you first unbox it (ideally via ethernet) and then disconnect it. If you don't like Apple TV then your streaming box of choice.

Can you update via USB? I know my (couple years old now) Samsung TVs have firmware downloads available so you don't even need to connect the TV to anything.

Yes. I've owned a couple Android-based Sony TVs in the past decade and they both support updating firmware via USB thumb. They also support installing/removing packages with ADB, just like one would with an Android phone, in the case that there's some offline app you want to use on it. The newer models also do a neat thing where if you have external speakers hooked up, its internal speakers can be repurposed for center channel audio which is super cool.

I'll echo the Apple TV + Sony TV combo. It's very solid.
