Also, one can easily imagine a cheap, handheld controller for in-flight games. Like the headphones, it could be free (or paid) and deliver a more immersive experience. I would personally love to play something like Street Fighter in-flight, but also a nice brain game where I could high-five the person next to me. Otherwise, we may not even talk through the entire flight. Games can connect and unite people, which is sorely needed in a world of inner-worlds.
