I look at it like this: what problem does this product solve?
The iPod - solved the problem of how to carry your entire personal music collection in your pocket; portable music players were a thing for decades before.
The iPhone - combined cellular phone, portable music player, and (for many) portable computer/PDA into one device that worked seamlessly.
The iPad - portable television/media consumption device; main computing device for children, the elderly, and those that only have basic computing needs.
Vision Pro - ?????
As I see it, with this first headset,
1. It will be the best device for 3D modeling and CAD related work, artists, architects, car designers, etc. once the software is built for it
2. It's a solid device for software development with unlimited windows and pretty great ergonomics since you can walk around and put the screens wherever you want
3. It's a compelling movie experience, I'm not sure about the best.
4. games tbd, depends on developers and if it can offload compute to a mac to run full PC or PS5 VR titles (M2 is not powerful enough)
5. it will open up new ideas for entertainment media forms we haven't even thought of yet (like Disneyland experiences in your house)
My prediction for the future,
1. The vision pro will replace a wider and wider set of mac technical workflows, essentially this is the next generation macOS and studio display, blending hardware and software all in one virtual workspace. You may still have a mac studio or macbook as a wireless compute unit.
2. In 3 years or so as it improves and gets cheaper it will replace iPad related activities like content consumption and games and be more mainstream in the house.
3. Maybe 5-10 years from now it will be so light and mobile it can be used outside and then replace iPhone activities.
