"Even as they face mounting losses, airlines are trying to find new ways to make flights more fun. The latest offering: hand-held entertainment devices that display movies, books, newspapers, magazines, TV shows and games. Personalized electronic entertainment has been around for several years, mainly in the form of seat-back video offered on low-fare airlines like JetBlue and Delta Air Lines' Song unit. But built-in systems are expensive to install and don't always work well. Enter lightweight, portable devices like the Pea -- Personal Entertainment Appliance -- the digEplayer and the Yes Solo machine.American Airlines, the world's biggest carrier, will begin testing the Pea soon. For about $8 to $10, coach customers will be able to choose from content such as games and magazines."Sounds interesting. Apparently, for a few more bucks, one can get access to early releases as well. What do you guys do when traveling? I typically listen to music and read a good sci-fi book.
