I have been running a Scala Rider B/T headset for nearly a year. It works VERY well, but isn't stereo--that's my only problem with it. I have an IPAQ and the PDA can double as an MP3 player, even a video player--PERFECT for those long night-time trips! :lol:
Actually, there's a product for PDAs called Pocket DVD Studio that allows you to rip movies to be able to run them on a PDA--they can be as little as 128M and you can get 6 movies on a 1g SD chip. On a long plane flight my kid and I watched LOTR--with a headphone splitter so we could both get the sound.
You can watch the movies on the PC as well but the picture will be the size of the PDA!
BTW, I only rip DVDs for the PDA that I already own.
