It's not the hardware - it's the software. I went all in on Amazon Echo and Dots. I have them in my living room, office, bathroom, bedroom.
The ecosystem that Amazon provides is far richer than Apple can hope to provide. Google does seem to be better positioned.
Even if the hardware is amazing, I don't want Apple music (I have prime music) the voice assistant is no better and I have serious doubts about the integrations that will be available.
Whats going to make this DOA is integrations, it's not in Apple's DNA and its going to be the best sounding, most beautiful, most seemless voice assistant nobody wants. I hope I'm proven wrong.
