It seemed silly to me, but then I remembered how Apple works. Create something that you can't have. Oh an M5 chip in something I won't buy. It would be great if we had M5's in MacBooks -> want. Apple manufactures desire first before satisfying that created 'new' market. Last time I recall was the iPad Pro's even before they started getting useful as very few people buy these. Scarcity sells.

The math isn't how many people will buy Vision Pro M5, it's how many have nots can be created by putting it in the Vision Pro.
