This may be a great product. But regarding price, I see many writers imply the same as you — that the price will go down.

But Apple has no real track record of lowering prices. The iPhone 14 models are significantly more expensive than the original (adjusting for inflation, they're still not cheaper). Even the cheapest iPad is similarly priced to the first. The same goes for AirPods.

As for size, none of them has shrunk significantly either.

Why do we expect any different from the Apple Vision Pro?
