The only place where you can actually buy them off the shelf

Sort of . . . Consider this conversation I had with an employee at Best Buy.

Me: I'm looking for the Rio Karma.
Him: ummm, I'm not sure I'm familiar with that. What is it?
Me: It's a hard drive base mp3 player.
Him: Oh, you mean an iPod!
Me: No, it's better than an iPod. Longer life, plays wma, ogg, and flac in adition to mp3. It also has cross fading and numerous other features, including gapeless playback.
Him: Really? That sounds cool.
Me: Yeah, you really ought to check it out. I have their car player and it's absolutely amazing.
Him:It plays CD-Rs?

Yup, when we're having to sell the sales people on a product there is clearly some kind of lack of marketing. Incidently I did get the guy pretty excited about the Karma and I think he actually picked up the box and looked at it.
