I started out this way, but I dropped the DVD drive for a 2nd battery. For trips now I load my laptop up with my backlog of TV shows from my ReplayTV. I can usually pull about 10 hours of movies and shows on my laptop quickly and have plenty to watch on a trip. Nothing grabs the attention of the airline traveler next you faster than watching The Man Show on your laptop.
