It is a good thing. But I would advise only to buy it if you are an Apple Music subscriber or have an extensive iTunes library. You also definitely need at the very least to own an iPhone. It sounds better than my Sonos play 1 and at quieter volumes better than a play 5 even.
However, if audio quality is your own then Naim products are amazing. I have a Naim Muso now and it is head and shoulder above the competition.
The HomePod is the best sounding smart speaker though. Looks good too.
