Very interesting. I've only watched 25 minutes during lunch but two things I picked out so far.
1) If all the data Microsoft had suggested most people were watching Netflix on their 360, was this because people were buying the console as an alternative set top box to do so rather than for gaming? And why was nobody seemingly playing any games? The Xbox 360 had many great titles to play. And this would have been data from the mid-way point in the 360 lifecycle when Xbox One design is already in progress.
2) John seemed to think that the Xbox Series X is having the same UI as the Xbox One family (which we know is true) but still running at 1080p? On the XSX? That's shit if true.
And a 3) They mock the Xbox One UI design with its app snap features but it looks like Sony is going to be doing something similar (at least with overlays) for the PS5.
