Having to watch Beethoven 2 as your in-flight movie is bad enough. But if you’re a frequent flyer, that may mean sitting down to the third screening of Beethoven 2 in a month. Give them control over their entertainment destiny with one of the new portable DVD players. Weighing a couple of pounds at most, they have high-resolution LCD screens and can play music CDs as well. They’ll be the envy of their seatmates.
