For those worred about no apps, they 99.99% likely will have apps(I don't work there but I work enough in the ecosystem), but must be specifically designed to fit that form factor like Apple TV/Vision pro/Apple Watch, with their own shared and exclusive API. Tightly controlled UI/privacy/UX. I'd imagine there is a quick path from going from AppleWatch to this.

Is iffy if they will allow a run it like on iPad but you see iphone form factor on it. The UX likely suck bad if they go ahead and takes away from the form factor. Plus companies like FB may just leave it at that like how they did with instagram for ipad for a decade.
