Not to put too fine a point on this, but by talking about the size of the market, you do realize you're committing the exact same mistake as Dvorak, but in reverse:
>Apple Inc.'s past successes have been in markets that were emerging or moribund. Its biggest hit has been the iPod.
Recency bias aside, Apple clearly has experience to take on markets like this.
>doesn't solve any existing obvious pain points.
I mean, if you pay attention to any of the people that have tried hands-ons, they all say the UI interaction is leaps and bounds better than anyone else. Hand tracking, clarity, and pass-through too - this isn't a Meta Quest competitor, it's an improved Varjo XR3 for half the price. This price isn't really a blunder as much as a signal as to who this is for.
But really, the point is that this isn't the device Apple wanted to make. They wanted to wait another 5-10 years to get the miniaturization and price down so it can just be a pair of glasses. But they don't have that luxury; Zuck is trying to own the market, and Apple needs developers now rather than later. They know this device won't have high volume (and they've told shareholders that for months) but they're investing for 5-10 years from now when the tech is at the point where it does.
>If I buy one, what device can I throw away?
I mean from the way Apple is currently marketing it, the answer is "Your tablet, probably laptop, and even TV, (and eventually, your phone)"
