It's certainly not a success, but Apple just beat Meta in almost every way except price while not burning O(10B) in the process. That gives me a lot of confidence that they will dominate this space if it ever takes off.
It has been reported Apple spent an estimated $15 Billion on research and development for Vision Pro, that's a lot more than 10B. Meanwhile, Quest has sold over 20 million units. Apple might have beat Meta in "almost every way except price", but for now Meta has Apple beat in every way that matters.
Apple spent about as much on AVP as Facebook did on Quest, starting about the same time (10 years ago) and all Apple's done to date is release a Quest Plus with slightly better specs and premium materials for 7X what Facebook charges and that's why Apple only has tens of thousands of monthly AVP users and Meta has about 10 million monthly Quest users.
I don't think it's a huge surprise that a company that has been designing hardware and selling it to consumers for 30+ years beat another company for which this was both the first hardware they ever designed and the first time they ever tried to sell something to consumers.
