I typically load my iPod with a few hours worth of movies/tv shows, but I still enjoy IFE if it's AVOD. Otherwise I'm limited by battery life and storage space. With AVOD I can watch things I may not have had a chance to otherwise (I rarely make it to the movies or the video store). Plus I can then save the iPod for the times when I'm sitting in the gate, or stuck on a bus, or train, etc.
