The Xreal is a nice device. I got the first gen for $199. I'm able to plug this into the MacBook pro and watch Netflix in bed. The fonts do look a bit blurry and small. I don't think I can work with it full time. I don't have myopia (or my number is small to notice).
I wonder specifically if their high-end devices (Xreal One Pro?) would be OK for some amount of coding work, or is it just a movie-watching screen. Even if it is only for watching movies, it might still be interesting for flights, though.
