I has been available for what, about two months, and you're whining about App Availability?!? Gimme a break!
Yes.
See, I don't know whether it was intelligent foresight or accidental good fortune, but the iPhone got three things exactly right in its initial release: it *didn't* have an App Store, it *did* leave the door a smidge open for people to install apps on it *without* an App Store, and it got a lot of features right that made the phone desirable irrespective of that.
Listening to music on a phone is a default thing now; in 2024 we probably use a phone to do that more than any other device...but in 2006, everyone was carrying around both a phone and an iPod. While the original iPhone has a small screen by today's standards, compared to other portable video players of the day, it was quite an improvement, so watching videos away from home was finally viable (you hadn't LIVED until you tried converting video for WinMo devices). No stylus, threaded text messaging, a web browser that was actually useful, and native support for IMAP email, even for free Yahoo accounts (then dominant because Gmail was still nascent) were all massive improvements that non-techies could appreciate. ...and, roughly eleven seconds after some techies got a hold of it, we ended up with the jailbreaking scene. That's where Labyrinth and Tap Tap Revolution (Revenge) and dozens of others got their start, and it was that underground scene that drew in developers. By time the App Store came into existence, many of those developers just shifted over their app from Installer.App or Cydia to the App Store.
Essentially, the iPhone's success came from the fact that it had plenty of desirable functionality without third party apps, and it enabled an underground scene of developers to get the app ecosystem started by time it was official. The Vision Pro headset had neither of these things going for it...if it's anything beyond the ability to function as a super expensive monitor for a Macbook, I couldn't tell you what it was. Consequently, the Vision Pro *needs* an app ecosystem to justify its existence in the way the iPhone did not...and it isn't there.
