I doubt that's enough resolution for comfortable text editing like I believe the person you are replying to is envisioning.
Back when I was working on hololens 1 stuff, I was very surprised how the bad resolution wasn’t actually much of an issue. I think since we’re always slightly moving, our brain makes some kind of natural temporal antialiasing ? And it’s not awful like VR since it’s super imposed on the real world and not a feed of it
Pixels per degree would be diluted or concentraded based on the filed of view.
So you could have that resolution be a super crisp, but small region.
