Bear in mind that many younger people grew up with mobile computing first. So they're not as familiar with the "power user" desktop computing behaviors us older people have developed. Not dismissing that Google Docs overlay may be explained by any of the following: (a) learned behavior from mobile computing that very few things are configurable (mobile apps tend to have far fewer preferences on how things are displayed; (b) pop ups on mobile often don't close when clicked; and (c) they are used to operating with very tight screen real-estate. I think (c) is most likely. As someone brought up on desktop computing, I fight to eliminate anything that needlessly wastes screen real-estate such as bloated window chrome. But I think someone brought up on small screens might actually feel agitated by "too much" space.
