I actually think the Vision Pro does have the ability to open up immersive home theater experiences to more people. I don't know that it actually replaces a full blown home theater setup, but I bet it will get you pretty close while taking up far less space. People living in small urban apartments will be able to have experiences similar to those suburb-dwellers in their McMansions with home theater man caves.
We're living in a time where entire generations of people feel like they'll never be able to afford to own a home; that they're going to be trapped renting small apartments for their entire lives. In such a scenario, the main living area needs to be flexible, multi-functional, even if it's small. It needs to be a space for kids to do their homework while also serving as an entertainment space, often at the same time. How much would you be willing to pay If you put it in the context making small spaces feel larger, I could actually, in time, see something like the Vision Pro effecting the decisions people make on where they live.
And I haven't even touched on the idea that the Vision Pro could potentially replace multiple devices. I really don't see the need for having a mac nor an iPad if you have a Vision Pro instead. I'm not sure that will be the case at launch, but I think that's the road Apple is now headed down.
