Given they decided to announce this earlier they must have looked at the Apple XR spec leaks and will undercut Apple's efforts to attempt to sell their headset. The first new form factor of an Apple product is the worst one to buy (Unless you are a collector)
Meta is clearly far ahead in AI, XR and vision research than Apple is. But then the goal is obvious and it is the AR glasses. Either way, the death of Meta Platforms Inc. (Formerly Facebook) has been greatly exaggerated here.
We'll see about Apple's headset but the leaks only show that the hardware and the price is very underwhelming. The most important thing to look out for is the software. But no doubt that Apple will try to justify the high price at the last minute.
