Yeah that's probably a good estimation. To me the clarity is fine. I definitely recommend trying one before buying though to make sure you'd be happy with it.
Yes, I use mine many times per week for hours at a time, and my top use case is as the ultrawide theater sized screen for my Macbook Pro. I'm a software developer and the lack of text clarity doesn't bother me much. It's really not that bad. Of course it helps that I make the screen really big so it's easier to read everything.
And it doesn't put strain on my neck like others have experienced.
One bonus benefit is that with normal computer screens I have to wear glasses, but inside the Vision Pro, I don't. So when eye strain becomes an issue after hours of programming, it's very comfortable to switch to the Vision Pro. Much less eye strain.
