Well, I wanted more than a $350 egg timer that sounds great (and frankly was promised better/more). But it IS an AAPL product so I probably should have known that $350 for an egg timer is considered "a great thing" in the Apple reality distortion field and that I'm the unreasonable one for actually wanting something more than a beautiful device that really doesn't do what others do.
1) Get me an answer about something simple (that alexa and google assistant fire on with pretty damn good reliability) like "Tell me about the paul manafort issue".
2) *ANY* third party app data/task that isn't HomeKit. Integrations/skills - totally lacking, SiriKit is a joke on iPhone, it's even more pathetic on HomePod. Alexa can drive all kinds of things remotely and on its own, while HomePod can't even set a reminder unless my iPhone is on the same WiFi network.
3) Like I finished with above, even Apple's OWN ecosystem of things can't/don't work on it unless there's an iPhone on the same network. Sometimes my phone is in my car, it's dead, I forgot it at the office or home, whatever.
But you are correct: It's a brilliant speaker, but that is all it is, a brilliant speaker. *ALTHOUGH* even in that, no Bluetooth pairing support? Really? Yeah, AP2 exists, it's quality is ostensibly better, but sometimes I have friends come over with Android devices who want to play stuff and AirPlay 2 adoption sucks, soooo, no cigar on the HomePod. Even myself, AirPlay 2 itself is pretty damn buggy esp in larger WiFi networks, there are times I *wish* playing music off my iPhone would just use normal BT and not all the fanciness (and attendant things that also can go wrong) with more complex protocols like AP2.
Apple's whole thing is "our **** just works" (at least for me). It's never the fastest (despite the claims/reality distortion field). It's never the most modern (cute, the MBP just got DDR4 and 32GB and still has a keyboard that doesn't work). But I still buy it and pay the premium because, like I said, it just works without much fuss.
I've had way too much fuss, "I'm sorry, I am useless" from Siri, etc on HomePod, and not nearly enough "wow, it does this really well to forgive these other things". But if all you need to do is say "hey play this play list", it's probably the best sounding speaker in that price range that does that in one box without a phone attached. But it's not a smart speaker.
What are you asking HomePod to do? I've rarely had a misfire when asking for any music, timers, and general trivia questions.
