As soon as HomePod hit, it seemed obvious that the competitors in this space faced certain challenges.
For Apple, the biggest challenge appeared to be to evolve Siri to be as good as or better than Alexa in all functions that Alexa does with one of these products.
For Amazon, the biggest challenge was updating the quality of the speaker to be as good or better than the (apparent superior) speaker quality in HomePod.
Now ponder this: which challenge seems easiest to realize?
In other words, how relatively difficult will it be for Apple to rapidly evolve Siri to be better than Alexa to help justify the HomePod price vs. how hard will it be for Amazon to change the speaker? And note the latter could change the speaker and charge upwards of double+ their (oft-run sale) price and still be priced substantially lower than HomePod.
The magic in Apple being able to command an Apple premium is always in the software, not the hardware. In this case, I foresee Amazon being able to match+ the quality of sound of HomePod AND significantly undercut HomePod's price... or even spin 2+ Alexa 2s/Pros for the price of 1 HomePod.
This is akin to the long-term idea of an Apple Television. We all know Apple would have sourced the panel from Samsung, LG or similar. And those suppliers would probably put the exact same panel in their own-branded "case" priced without Apple's margin. Nobody could make an argument that the Apple-branded version of that TV had a superior picture because the panel would be the exact same panel. So what might justify the Apple markup? (Maybe) the unique software that would be exclusively available in the Apple version?
So back to topic. If one buys the above, it seems the challenge for Apple is to make Siri superior to Alexa in how it is used with this kind of product. Else, Amazon, Google, etc are all well capable of assembling the same or better hardware and pricing it lower than Apple. And if Amazon, Google, etc software is generally deemed superior, HomePod is going to be challenged to win over the non-fanatic masses.
That's no Apple attack or putdown- just basically pointing out that it appears Apple is trying to rationalize the Apple price on a hardware advantage (that is not yet objectively verified in the field). Yet Apple traditionally "wins" support for Apple pricing with superior (and exclusive) software. Putting a better speaker into this kind of product is probably as tough as putting better speakers in place of the factory ones in our cars. IMO, the challenge for Apple to "win" at about triple the (oft-sale) pricing of competitors is in making Siri leap well ahead of the next generation Siri's owned by the competition. If they don't do that, then it seems it's a match of who will sell comparable hardware for less... a game that Apple seems to be unable to ever win because Apple loves it's fat margins. Amazon, Google, etc tend to trade margin for share... just as PCs did vs. the technically-superior Macs long ago.
