Apple building homeOS from scratch for a home hub is a stronger signal than anything in the spec sheet, because it tells you they looked at what Google and Amazon built and decided the right move was to start fresh rather than repurpose something they already had. This is a very typical Apple move. Watch the industry, learn what works and what doesn’t, and then enter the space later than the competition with an offering that is equal to or better than (and occasionally worse than) the competition.
Just like Google and Amazon, Apple owns a full ecosystem. And they have a solid codebase with all of their device operating systems, so having a shared language for their homeOS makes a lot of sense. It’s a tricky time to launch new hardware due to component price pressures.
But I feel like Apple is a bit late to the game here. I’m an Apple-forward household; however, I do not have Apple speakers or similar devices. Instead, I have embraced Google Home, Samsung, and Amazon. I’m not really sure I can add more.
