Hmmm. You can tell Mr. Jobs doesn't get out in rush hour traffic very often. While it's illegal in most states, you'll find some idiots watching portable DVD players while on their commutes. I've seen at least 6 this week.
The cool thing about portable video in a vehicle is what happens in the back seat when you have kids. Quietness. No "He's touching me!" or "Are we there yet", at least for a while.
