To me, this is even a hard sell for those in the Apple ecosystem, like me.
It is (IMHO) too focused on being a great speaker for Apple Music at the expense of other functions and services, even within the Apple ecosystem. Smarts-wise, the HomePod version of Siri is less capable than the one on my Apple Watch. No ordering anything. Limited access to the internet. It's not even a great Apple TV speaker. If I connect my Apple TV to it and then later that day, stream Spotify to the HomePod, they don't automatically reconnect. Again, easily fixed if it had a audio port that I could physically connect to my TV to take advantage of that great internal tech.
I'm confused because I don't see the business signals for the need for such a device. Before Apple entered the market, (again IMHO), music players sucked, computers sucked, phones sucked, tablets sucked, smart watches sucked, BT headphones sucked. But, the smart speaker market? Especially a speaker focused on Apple Music? I'm not seeing it.
