Until ipod support was available for the car it was a pretty useless item to me. I'm all about cd quality sound, and even copying onto my ipod at cd quality (1000+ kbps) I can keep hundreds of cd's with me on my 30gb ipod. It also saves the hassle of burning cd's for stuff that you are kind of into at the moment, but that isn't something you want to buy the cd for just for that one song. Definitely, to me, a worthwhile purchase, and it saves the clutter and hassle of carrying a bunch of cd's around, and it lets you take take better advantage of your display instead of rolling around with "NO TITLE" displayed for most of your stuff, if that matters to you.
