why buy that I already have an ipod

Buy it because it doesn't replace the iPod, it *enables* the iPod; and ideally the Rios and Nomads too. It's one step toward having your HDD portable be your only music source. Use it on the go with head phones, use it at work or home with one of those docks with speakers, and use it in the car with the control box I'm proposing.

And it would appeal to the non-DIY group who are unable to make a "h4x0rd" 486 box in the trunk. It's something that could come bundled with the car (ideally) or you could have your local installer put in. Imagine the conversation between car salesperson and buyer:
sales: "So, those are the options. By the way, do you have a Karma, iPod, or Nomad?"
buyer: "Yeah, actually, I love it."
sales: "Well, how about using it to replace tapes and CDs in your car! For $399 extra, we can add the interface module to your new car. No headache, just plug it in and all your songs are there."
buyer: "Hm, that's kind of a lot, but... ah, it's worth it. Put it in."

Seems like a logical need that's currently not being filled. But I'll stop rambling now because I have no way to bring this to fruition; at least not right now.
