Just because I said the HomePod doesn't seem very useful doesn't mean that I think the UE MegaBoom is useful. As I've said before on these forums several times, any time I say "Hey Siri" several devices within range of me light up. My wife couldn't even use the HomePod to access her things as it would only recognize me. The point of a communal smart speaker is that more than one person could use it. This is zero different than any other Apple product that I own except that it has a nicer speaker inside. That might be useful to some who don't already have a speaker, but it's only kind of useful. Most people already own several speakers.
Then, when you factor in how much worse Siri is in many situations answering basic questions compared to competing platforms, you have to wonder why a regular person would buy this. I like that it has better security and privacy behind it, which is why I refuse to buy another brand of smart speaker. But in it's current state, the HomePod is not worth purchasing IMO. And I'm the guy who owns every Apple thing. Hopefully software updates will make it more useful in the future. Most people would be better served buying an Apple TV for less than half the cost and plugging it into their sound bar. Most people aren't audiophiles. Then they get a nice TV experience and can stream Apple Music and whatever else to their sound bar easily. I just don't see this thing gaining much traction for a long time. I'm usually pretty optimistic about new Apple products but I just don't see it here.
