I believe there's a mistake in this article. While using airplay to mirror the Vision Pros screen to a Mac is limited to HD (720p, not 1080p) using sidecar to bring in a virtual monitor for you Mac into the Vision Pro is 4K.
This is such a mistake because Apple likes to create new product categories rather than expand on existing. They should have made this thing a peripheral, it could then work with a more powerful processor(s), anything from an iPhone 16 to a Mac studio, and it could be created toward standards. Ok, the last part is wishful thinking. Anyway, it's too heavy and bulky, going to be quickly outdated, basically e-waste in two years except for the Apple fetishists, who are already spinning the fact that it's custom fitted as an advantage, rather than the obvious problem of it not being adjustable/shareable.
The long term of this product is going to be a display with sensors, which can be a separate product, and an AI/renderer, which can be an external device. It's better to split these functions, especially at the start when hardware is under rapid development.
At the start of sales in the USA, Apple finally confirmed the full specifications of the Vision Pro. The iPhone manufacturer still had a few surprises in store, such as the option for memory upgrades or the details of the built-in processor.
