I hate seat-back video on planes. I really, really don't need some flickering screen a foot from my face for hours on end. My only interaction with them is whacking the off-button until it finally acquiesces. From a strictly selfish point of view, the only positive feature I can think of is that they can hypnotize some (but not all) children who would otherwise be annoying.
