What would I do when I want to watch DVD's on an airplane? [/b][/quote]

Hey, John, I'm curious about this (this is a serious question, not anymore of my trash-talkin'): how do the movies look on the i7? Maybe this is a better post in the i7 forum, but since you brought it up, I thought I'd ask. Is the sound good as well (granted, the headphones must deliver in that area too)? Is it choppy at all? How long does the battery last when watching a converted DVD?
