Panasonic DVD-L50 Portable DVD Player
Beats a laptop with DVD drdive
I travel...a lot. My first pass at watching DVD movies on planes was a high-end DVD drive for my laptop (connected via PCMCIA). It was nifty, but jerky, and the sound wasn't great. My wife and father-in-law got me this  unit for my birthday. I'll never watch a movie on my laptop again --  there's simply no comparison. For those of you who question the value of  the Panasonic when you can buy a laptop with DVD -- you're just plain  wrong. This is made for one thing only: Watching movies. And it performs  that task splendidly.
