In my experience, practically nobody. I agree that the Vision Pro is a technological marvel, but it's still a solution looking for a problem, and it's striking to me how even Apple had a difficult time presenting actually compelling use cases in their videos.
To be clear, I think there are some viable uses: gaming obviously, and potentially media consumption, but even there this solution is so much worse than a home theater system (as another commenter mentioned, I can get a group of people together in my house to all watch a movie on a big screen TV that costs much less than the headset that each of my friends would also have to own).
The difference, IMHO, is that those with pre-iPhone smart phones were largely business users who didn't have a choice. Not that there weren't exceptions - I'm sure many had personal smart phones - but I vividly remember (in both Europe and the US) conversations with friends where the idea of paying for a data plan was considered the height of absurdity and would never happen for personal use.
Retconning phone history as if there was nothing between flip phones and first iPhone, or that transition time was short is dishonest.
(Also, Blackberry was big for UK teenaged girls due to free BBM)
No, not really. Like Steve Jobs said, smartphones weren't very "smart". Most people did not have blackberries (those that did have Blackberries, were mostly business users). The rest of us that were technically savvy were playing some crappy java games(the ones allowed by mobile carrier stores), and browsing the web with WAP browsers in our flip phones. Most people were not even doing any of that. And why would they? The experience was terrible.

Using the same metric, people already use VR headsets, and just "want them to be better". Sure, the marketshare is a fraction of phone marketshare(https://www.statista.com/statistics/677096/vr-headsets-world...). But we can argue that most headsets are tethered to high end PCs, Meta's version is one of the few decent standalone versions.
Apple's device has lots of potential. It's all about the execution now, and subsequent devices.
