I'm digging my HomePod. The speaker itself is excellent, and while Siri has its limitations, the features it does include are working solidly. (I do wish it could tell me my calendar appointments though.)
One unexpected benefit of the HomePod, which sits on my desk in my home office, is just how well it works with iTunes on my Mac. To play music from iTunes to your HomePod, there is a simple toggle in iTunes for the Mac. You can set volume from Mac and seriously upgrade your tunes. I always need background noise while working so often I’ll play the sound of the ocean or a thunderstorm when I want to focus. Thunder from the HomePod turned up literally shakes my desk. My iMac never did that.
