I can understand this being a differentiator to other AR/VR products, but that is not exactly what the comment I replied to said, they said the “killer app” was the ability to buy it at an Apple Store. Short of a few folks with too much extra cash and curiosity, just being able to try it before you buy isn’t what I would refer to as a killer app. The “killer app” is what gets the main market populace to the store to even consider it.
