That would be a giant step backwards. What if you`ve already seen the movie offered? What if you have to go to the potty? What if you want to take a break to eat? What if you`re sitting behind Carmen Maranda and can`t see through the fruit?
You are correct about carry-ons though. As they proliferate, the need for IFE of any sort will diminish. And if sales of digital movies on line increases, that will have an impact. However, a lot of people have portable DVD players and MP3 players, and it doesn`t seem to have impacted much.
But I KNOW nuttin`!
