The "killer app" here is to have an infinity-sized 'screen' for anything the average user was already going to do with an iPad or Apple TV. The hardware's just not good enough yet, in terms of lightness and comfort, for the average user to put up with as more than a novelty.
The extreme majority of users is perfectly happy with two 24" monitors (actually, the extreme majority is happy with a single 13" monitor). "Infinite monitor space" isn't something that will sell a large enough numbers of headsets to prevent the cancellation of the next iteration.
Do you think it's plausible the hardware will ever be good enough?
People aren't really that happy wearing even vision eyeglasses, and I don't see any realistic chance we will ever be able to have something with the capabilities of the Vision Pro in a form factor as small and light as eyeglasses.
