How does this follow? The original Newton launched at $699 in 1993 dollars ($1551.80 in 2025) and the first iPhone came out 14 years later at $599 in 2007 dollars (926.76 in 2025). Your comparison doesn't even work with the MacBook: The original Powerbook 100 would be almost 6000 dollars in 2025 money and only the most extreme versions of the MacBook Pro that the vast majority of consumers would never even consider cost that much.
I get you're just trying to say Apple is expensive, but history suggests that if a vision pro successor does eventually exist, it will cost less, even if its still expensive relative to other products available at that time.
