Your mistake, like so many other folks, is in your incorrect assumption of: "VR headset when the market has already decided that they only succeed and sell when sub-$500."Amen. Apple releasing a $2000 foldable in a market of other $2000 foldables would be excellent compared to releasing a $3500 VR headset when the market has already decided that they only succeed and sell when sub-$500.
Realize first that the AVP is not simply a "VR headset." Take some time, do more than one brief test session, and look at the AVCP as a new-tech test bed, which is what it is. The fact that more than 100k units sold at $3500 is pretty amazing really; most of those buyers certainly did not drop $3500 because they were looking for a "VR headset."
As Apple proceeds with the AVP a big marketing challenge will be to educate the public that has been preconditioned to think that goggles one puts on one's head are always simply the [IMO often crap] "VR headsets" that have been sold for years by Oculus, Meta, MS, etc. The reality [intentional pun] of AVP is quite different, but understanding does take some thought.
