I bought it on launch day, and I still use it at least a couple times a week. I also pretty much always take it with me when I travel (along with my MBP). Frankly, I'd use it even more, but because it's a fairly anti-social device I prefer to use it only when I have meaningful alone time. If I were living alone by myself, I imagine it could be a daily device for me.
My main use cases are Mac Virtual Display, movies/entertainment, PS5 gaming [0], casual browsing, and -- most surprisingly -- reading. The first few are pretty self-explanatory, but reading is one of my favorite unexpected niche use cases. It's really nice having a floating book (via Apple Books) perfectly positioned at eye height in front of you in your favorite virtual environment, listening to music of your choice. This use case didn't really take off for me until the recent dual knit band fixed the comfort issue. I dabbled with reading in the Vision Pro before but the comfort level just wasn't quite there yet. The new band is good enough to make this one of my favorite ways to read today.
[0] I use the Portal app for this. It lets you stream PS5 games into a gigantic screen inside the Vision Pro. I combine it with a Dolby Atmos surround sound speaker setup in our upstairs game room. It's truly a stunning experience. The only reason I wouldn't declare this the gold standard way to play games is because it currently relies on WiFi streaming, which introduces some input lag. The lag tends not to be an issue with the games that I play, but it's enough that you wouldn't play competitive twitch shooters with it. If Apple had just allowed you to plug in an external device via HDMI, this would hands down be the most impressive gaming experience out there. I'm personally very sensitive to input lag thanks to years of low-latency PC gaming, but I know not everybody is. If you're not, you may be even more impressed by it than me.
