If you are trying to find a great way to swap music and videos with your friends when you are on the go, the miShare is the way to go. Now you can do this without a computer and at the push of a button. The miShare is a handheld device that acts like a little hard drive and swaps info between iPods.
You simply have to plug in two iPods into the device and choose the files that you want to copy. Individual songs take about six seconds to transfer, and music videos take less than a minute. It's a great and hassle-free way to share music. It's currently available for about $100.
