Whether the "incredible speaker" part is true remains to be seen since the thing hasn't released yet but you can look at a lot of the features and they're very music-focused.
It's more competing with a Sonos than it is with an Alexa in my mind, the Siri stuff is just lagniappe.
Incredible by what standards? It's not even stereo. Nowhere does it mention perhaps the most important metric for audio quality, namely RMS audio power output. The tiny size alone pretty much guarantees that the amplifier will suck.
I'm very confident that e.g. a combination of Klipsch R-15M speakers, Yamaha R-S202 amplifier and a Chromecast Audio will knock its socks off. And that's a setup which you can order on Amazon today, it costs exactly the same, and it can do perfect multi-room out of the box.
The current breed of class D amps are shockingly small and and have pretty decent audio specs(thd, rms, etc). Unless you are expecting a 50lb analogue >500w audiophile quality amp, I’m not why you would assume the size == low quality.
So the idea of just having a single device that automatically integrates with your phone, etc. is appealing to many people.
I was previously considering a Sonos, but the Airplay2 support will be baked into the OS so I don’t need to use a clunky 3rd party app.
It's connected to my existing nice hifi and speakers. I have a choice of clunky 3rd party apps, and some not-so-clunky.
It's possible the HomePod's clever design is as good as they claim, but I'd guess the same money spent on normal hifi speakers will give better sound.
Do not expect everything smooth sailing with Apple software. Currently when I AirPlay video to AppleTV, I can not use the remote controller to pause and play as there will be no sound. I suspect one reason for the HomePod delay is due to bugs.
Apple's main real advantage is lots of the high-disposable-income market is heavily invested in their ecosystem. The big ecosystems are real competitors, but the individual offerings within them are rarely direct competitors because the utility of the individual offerings depends on degree of pre-existing investment in the ecosystem.
For this reason, Apple will probably be one of the few western 'tech' companies who will most likely always have a foothold in places like China.
Apple has had the MSMs attention for so long it is silly. I have seen articles about Apple products in places that normally could not care less to cover consumer electronics or computers.
Basic thing is that Apple has long been the go to computer for doing media production, and thus the people writing for MSM is more likely to notice Apple news than other tech news because it affects them directly. And thanks to the typical fan myopia, if it affects them it affects the world...
Personally, I use Apple Music and am looking to do more with HomeKit, so it adds a few things there.
