Education and games seem sensible and I already said there may be some commercial uses (although I can't imagine them ever being good enough to want to use for 8 hours a day). Nothing else you listed there offers enough of an improvement over current phone and watch based alternatives.

Outside of education, games, and commercial uses, I don't think they will be able to overcome the glasshole factor.

It's going to be a big market, but I don't think it will ever be as big as cell phones are today.
