Correct. All of those products were pretty crappy when they were first released and then got very good. In the case of the iPhone, I think it was like the third revision when it got good. The iPad comes to mind as one of their only somewhat recent products that was really good right from the start. That one still benefited from being more or less a giant iPhone and it was years before it really came into its own. For at least the past 25 years, their initial forays into a new category have been marked by potential that isn't realized for several more years. I think the Vision Pro will be fine.
