The importance of pause

I have come to appreciate that most important button in an airplane is 'pause.' This is especially the case for long-haul flights. Whatever you are using to watch a video requires this. Not only can this allow you to go to the bathroom or sort out any food thrown your way, it is the only way to deal with the constant interruptions of children. It is the key to sanity.

This means you need a laptop, video iPod or video on demand system on the plane. Nothing else will cut it. All of the value lies in the 'pause' feature.
