I think at the moment it lacks a lot of use cases, but even in this first generation, the movie watching experience is astonishing. The 3D IMax size screen in your own space is quite incredible to see. As a first generation product it is quite something, but it is clear to me that this is where the future is. Apple will get it to the point where it delivers a must-have experience IMO, and of course the price will come down.I think that AR will eventually see regular, widespread use -- I'm less convinced that VR will ever be more than a niche (at least until technology has progressed far, far beyond anything we are remotely close to being able to make today).
I've also used the Vision Pro, and while the tech is impressive and a step up, it still has the same fundamental problem as other headsets. It just doesn't offer much that can't be done (and often done better) with existing, cheaper products (this is where the Mac comparison falls apart).
Until a company is able to come up with software etc. that offers a better experience for everyday use/regular tasks than a computer (or even smart phone/tablet for some things) it's not going to become a mainstream, daily use product.
That was my biggest takeaway from using it -- that even Apple hasn't yet figured out a way to make it actually appealing for general use or an improvement over existing tech for most tasks. A laptop is an easier/better solution for most of what the Vision Pro offers (there are obviously some exceptions to this).
While sales would surely go up if the price was reduced, I think actual usage wouldn't be significantly different than prior headsets. It would be used occasionally but mostly gathering dust for the majority of buyers.
