You're such a film buff you can't leave home without your favorites. You're going to a desert island and you can only take one gadget with you. Or you and your kids/parents/girlfriend/airplane seatmate have deeply conflicting movie tastes. What you need is a portable DVD player (that also does audio). Here's a good deal on a lightweight one with built-in 7-inch screen, Dolby Digital and stereo speakers. Operates on Lithium ion battery, AC or car charger.
