I also caved and bought a pair.
The smart watch used to be pretty obscure and known as being a tech geek device, but now I see most people wearing an Apple Watch as opposed to not even wearing a watch it all just a decade ago.
as for apple vision ar is the future no doubt, that seems obvious like wireless earbuds did. Vision pro tho imo is a devkit, but the fans will buy in anyway id guess. wait till they release a more consumer focused model and then itll be more obvious AR is working out.
And I have no idea why you are talking about dropbox and flying.
Apple's new device will not fail because there was some comment in 2007 on HN related to dropbox that pointed out alternatives (but even that commenter said it's good idea for windows).
