Agreed.A “gadgets off” policy means you will be paying attention to your surroundings. This means you will respond to them. Should there be an emergency, you may faintly remember the indications from the people working on the plane.When you don’t pay attention, you become the douchebag who doesn’t want to move because he’s too busy playing Angry Birds Space on an iPad. You become the idiot who is playing music so loudly through the headphones that everybody hears it.Having devices turned on through a flight offers people yet another chance to become assholes that get in other people’s way.

Opinion: Shutting down your gadgets at takeoff and landing: not such a bad idea
