Have an idea of making a In-Car Entertainent system using a raspberry Pi. My plan should allow it to act as the cars radio, play mp3s, sat-nav. Could be used to control other things. I don't own a mini but i have thoguht of this idea. Other stuff could be done like security, controlling Heater, hands-free phone calls. Do you think it could sell? I think the possible market price would be £150. Or am i just crazy.
