I like the orange button, at least with the current watch color. I think it goes with the aesthetic of the Ultra and the way Apple marketed the Ultra as a more rugged, more advanced watch for outdoorsy people.
It’s not a subtle choice, but I think that was the point.
Maybe they could tone it down and make it a colored ring around the action button, similar to the way the cellular watches used to have a solid color on the Digital Crown that was changed to a color ring later.
I partially agree with you. The problem is that the wifi router requires an Ethernet cable to connect to the modem which limits where you can put it.
What would be cool is to have a base station that’s just a router (maybe with HomePod functionality), but then add-on mesh network hotspots that work as HomePods. These would be a lot more flexible for placement.
