What do you do for music on the go?
I don't have anything other than a portable CD player that I bought for my car about 8 years ago. I don't use it much but it's still working. My truck is 6 and a half years old and only has a radio/cassette player in it so that's where I keep the CD player.
I've got a USB key for moving files from home to work but it's not one that plays music. I'm thinking of buying a music player, especially now that those sexy iPod Nanos are out from Apple Computer, but I doubt that I'd use it that much.
I have nearly a thousand MP3s and about 500 CDs that I could rip for more files so there's plenty to play but I suspect that, like the portable CD-player, I'd just not use it.
So in addition to what do you do for music, what format do you prefer to use? I've only used MP3s though I think I have something that rips in the new MP4 compression format.
