> Without a doubt I'm excited about lightweight AR glasses that I can wear in public. My non-expert opinion is we're still a few years away.

Not the same type of AR, but the Even G2 look very promising. Can't use them as an external screen, they're more of an assistant with notes, live translate, app ecosystem, etc. I imagine they might be useful as a moving teleprompter.

I own a pair of the Even G2s (with a prescription) plus the R1 ring - they started out a bit limited, but they recently added an app store for developers to create HUD applications for which has been fun.

They get a B+ as daily glasses, but if more than one of the "killer features" (e.g. teleprompter, conversate, live translate) really gets your attention they are worth it.
