The Future of Apple's OS

I don't know if it would have been straight away. Because I mean, maybe I'm not casting my mind back correctly,. But I don't even think we were talking about this kind of stuff then.

You'll be able to read books in VR. The words are around you. Is there like a physical book in your turn in the pages? Like, what is that?
