I guess this is where you have to decide your market. If you use the PC as your main music source (from CDs or wherever), the product will remain niche for a while yet, as the word MP3 still scares off a large chunk of potential users, let alone the complexity of ripping all your CDs, undocking your car player, connecting it to your PC, uploading and then taking it back out to the car. If you want the mass market appeal and the big sales volumes/cheaper prices that that hopefully means, then you need to have an easy way to get the music onto the unit. And a friendly CD slot is probably the most easily understood.

That's not to say it can't still do all the other things and more for those that want it..... If the mass market can get the price down, think what that surplus cash could buy instead!!
