Immersive-ness doesn't only come from just the screen, but also from the fact that you can't multi-task (one could say this is a sad state of my attention).
I play various kind of games. My main usage is "sport", with synthriders and beat saber. I love story telling/puzzle games, though they are quite costly (like 30€ for 4 hours of game play) so that doesn't account for a lot of play time. But I also like a small Cities Skyline (Cities: VR by the people from Cities Skyline), Deisim where you play a god, and Derail Valley, where you drive a train in a miniature world.
As a software engineer I have tried using it for other stuff than gaming, but even though it feels cool, I never found it actually useful. I can keep the headset 4 hours (and probably the whole day) without any issue (assuming no frame drop, which do happen when running from Windows, not in the Quest environment), so that's not the issue. Maybe with a better display resolution it could be better, but honestly I doubt it.
Just a word on the metaverse: I do think it can be pretty cool for socializing (Ready Player One is IMO not that far-fetched), though Meta's universe development still looks extremely primitive compared to everything else that exists. At this point, I think that a Meta Quest 3 with face emotion detection (and improved SoC and display compared to Quest 2), and let competing companies provide a good environment based on that hardware+OS (for instance Rec Room) would be pretty good, but I doubt that could follow Meta's bottom line.
