The fact that Tim Cook didn’t wear the display once during the demo is all I needed to create my opinion on the device. They also didn’t show any developers using the device - why? Probably because this is a glorified iPad and Apple continues to artificially lock down their Apple Silicon on some devices to not cannibalize the lower-tier MacBook offerings.
My guess is Tim Cook didn't wear one because Apple's media team didn't want every news article to use the screen grab as the header image (which is what happened with Zuc). They want the their manicured marketing material front and center.
