You actually have a good point there. In another comment here I was wondering where you'd actually need the automatic movement, since you are usually either close enough to move it yourself or far enough away to not be able to read or interact with the UI.
But situations like in the kitchen or maybe a work shop, where you don't want to touch the screen are where it would come in useful.
However would those be the places you'd want to put a $1000 Apple product?
The robotic arm part seems a bit gimmicky, not sure how much value that will actually add for the average user. I'd imagine that when you are using voice commands and are far away you don't really need it to turn towards you. At a distance you can't interact with the ui anyways and depending on how far away it is might not even be able to read anything on screen. And if you are close a normal adjustable arm would do the job just fine.
However I do think there is a market for a well integrated home command center and Apple with their walled garden approach is in a good position to deliver on this.
But it yet again seems like a dedicated device that is expensive might feature good hardware, but is limited to it's specific use case. Like the iPads that have the same chips as laptops, but Apple purposely doesn't give them MacOS to not cannibalize their sales of laptops.
The way control centers should imo be setup is to have the "brain" somewhere hidden like next to the router and then you have cheap screens around the house where you need them. Although Apple might love it, if people buy a $1k+ device for each room. Or instead of a dedicated computer for control one could just put their phone into a hub and have it serve as controller.
There are actually a lot of devices that work this way and several of them can even be installed in the wall where a two or three gang switch box would be. Most run some flavor of android or an embedded os and cost ~$200-300. So like $700 cheaper than what Apple wants to do for something that takes up counter space.
Brilliant and Tuya both make them as well among better brands.
I have the Brilliant one plumbed into my HomeKit via a zigbee bridge and it’s perfect
