Of course, I still don't think people would get it.

Are you kidding me? People are getting it quite rapidly. MP3 players are becoming more and more mainstream because MP3s themselves have saturated our society. I took mine to work for the first time last week, and I spent about 6 hours of an 8 hour day talking about it to various people who wandered by to look at it. In that one day, I generated 5 potential customers (one has 50 GB of MP3s, and is trying to fit them onto a 20GB iPod) out of maybe twice that number that I showed it to. Nobody that I showed it to cared that it had no CD player, and no one cared there was no tuner (of course, being in LA, that's not much different from a regular car stereo for what it's worth). Granted, once I started talking about hijack, their eyes glazed over rapidly...
