Saw this article on wednesday and bought the Xreal Air glasses on a whim to try it out. My take: it was close, but not crisp enough for all-day usage writing text. Returning them. If I were only interested in content consumption (video, especially) I would have kept them. Everyone who tried them in my house thought they were very nice.
Interesting. One key point: the “multi-monitor” feature only works on Apple silicon laptops for now (and Android phones).
