Critique #1 is about unknown implementation details, and we'll know that soon enough. In the meantime, an article on IEEE Spectrum says, "…journalists who’ve tried the device say it’s competitive with other AR/VR headsets, which offer a FOV between 100 and 120 degrees. That should place the headset’s pixels per degree around 50 to 70 PPD."¹
Critique #2 talks about the massive ecosystem advantage of the Apple Vision Pro, but I think the thesis — that HMDs will not replace PCs/laptops — is the wrong way to think about their value.
