>But what makes it worth the effort to learn a new SDK, or even buy a MacOs device to develop for it, for just a few thousands of devices?
This is a new official platform from Apple, not some random Google experiment. They don't do something like that willy nilly. This will be supported for decades to come now, and be the basis for who knows how many products. It's about getting in at the ground floor, a la iOS circa 2007.
The iPhone entered a market that was already huge and relatively mature, to further expand it in value.
AR/VR is far from that. I hope Apple's entry boosts it a lot further, but comparing it to the iPhone feels like there's only disappointment in waiting, even if it fairly succeeds like the Watch does for instance.
AppleTV was supposed to be a new thing with people developing entertainment apps and games that fit with a TV, not for general computing.
The watch added to the iPhone and had unique apps to take advantage of the sensors.
Neither of these were tied heavily to a macbook or other general purpose device. Unless you mean computing as in anything digital that runs code. Which I wouldn't really call a platform.
VisionOS feels closer to an AppleTV. New hardware with a different paradigm that needs a unique API and new apps built for it.
That said it does seem more like a supplemental device to your macbook + iphone. I doubt many are going to buy it with the intention of it being their main means of computing.
Maybe define what main platform of computing and core product mean if you could?
I hope you're right. I've had a US top 10 grossing game (Bowling) on Apple TV for years and the income it's not enough to pay one salary. We thought it could be a great gaming platform for people without PS/Xbox, but unfortunately this did not happen. Apple TV is probably great for Netflix etc though.
