I'm gonna step in and say he's prolly not lying. With a product this volatile and uncertain, he has to. I know CEOs don't usually have that much say on individual products but this one feels like his baby and his name is tied to it.
There is a good product in there. It won't be for everyone, but it could replace a laptop and even TV for a certain set of people. Single, no TV in the living room, maybe they have a projector, and someone that doesn't want a big ass screen on a desk to do work, or even someone without room for a dedicated desk, just a keyboard and mouse on a dinner table.
It just doesn't seem like they'll ever get the developer support they'll need by the time they get it down to 1/3 the price and half the weight.
I do know that the giant ultrawide screen mirroring is the feature Vision Pro owners are frothing at the mouth over tho. Then I could really see the advantage over a laptop + regular 27in monitor.
I know I'm rambling but also: they're being just as stubborn as they are with iPad: let these devices run Mac apps. That's all you gotta do. Let them run in an environment that requires a mouse and keyboard and we're good. I'm never gonna get iOS/visionOS ports of these little obscure photo manipulation/PNG compression/gif converting apps that are critical to my work stream. Lemme just run them anywhere. Wasn't that always the biggest advantage of being ARM/Apple Silicon everywhere!?
