Watches (both traditional and GPS for runners, hikers, bikers) and fitness trackers (Nike, Fitbit) were very popular prior to the Apple Watch. AR and VR are still unproven markets besides some games. Skepticism over Vision Pro is more reasonable than Watch. Iterating Watch was about improving implementation and delivering the features that we knew people wanted. Iterating Vision Pro is about creating a market that doesn’t exist yet.
