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 Anyway, it's too heavy and bulky, going to be quickly outdated, basically e-waste in two years except for the Apple fetishists, who are already spinning the fact that it's custom fitted as an advantage, rather than the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.
