Its not gonna flop, for the same reason that Apple desktops dont flop. Anyone educated in basic modern technology can easily see that for the price, you can build a custom desktop that blows any Mac one out the water, but people still buy them because of 2 things: styling and ecosystem.
Vision has both of those. People will conveniently ignore all the downsides of it, like they do with current Apple products.
I think this product will be a slow burn. They are getting developers engaged now and subsequent generations will bring broader appeal while the software will get more refined and apps will expand in availability. I don’t think it will be a flop it will just take a while to get going. And they must absolutely know this given the current pricing.
