"... each passenger will have access their own personal entertainment system."

Only a small point. Other than to display ghastly advertising, why not a dumb monitor that interfaces with your phone/tablet? It's not like you're going to be able to watch a movie. And if we're seven years into the future on this, I'll be wearing my Oculus Rift 4.0 anyway.

Maybe I'm just too disillusioned by the systems used in aircrafts with their awful interfaces, lag, etc.
