Somewhat unrelated, but this discussion made me go from "I don't see what I would need something that tells me tomatoes are tomatoes" (though realtime translation looks very useful), to kinda wanting it only to have a figher plane HUD-like display all the time (to be clear, minus all the fighting parts). Almost useless (at least the attitude and vertical speed part) but would feel kinda cool. Can see some value in having the heading all the time, and speed display to motivate myself to walk faster. (well they have directions which provides much more value than all that).

Though I don't feel comfortable having more Meta in my life.
