I already somewhat routinely spend multiple hours playing text-heavy games in it, and while I'm sure it would be a problem if I spent my whole work day in it, I really feel that the resolution is the only thing that would be needed to be bumped up to stop the little strain I do feel.

That's what annoys me so much. I feel like the tech is already here, but nobody is putting together all the right parts for some reason. We have high enough res displays (IMO), we have the tracking, we have the "AR" aspect, and we have the ability to project screens into the world around you, but nobody is putting all those parts together in one package!
