I think the main thing he's missing is that Apple isn't aiming for the Quest Pro vision of "Three big desktop OS screens in front of you" and is aiming for people to port iOS apps, where each context/window is separate in the 3d world, dialogs pop out, etc. Applications will natively be aware of how big the text has to be for each situation instead of trying to squeeze the 2007-era design of MS Office onto your eyeballs. Yeah they have the "project your Mac screen into this space" but that's obviously a bonus they threw in since they knew that there are not going to be enough productivity apps out there on day one. He's also mistaken about a lot of the text stuff he writes. MacOS X has always ignored font hinting. Macs (and some iOS devices even) will already render on a larger canvas and scale to fit the screen when you choose a different scaling mode.
