Now this is cool. Mitsubishi's iCar features an in-dashboard iPod nano dock. Just slide the iPod all the way into the slot where the dock connectors are and control it from the car's navigation display. No adapter, no transmitter, no clutter. For now, the iCar is only available in Japan. Here's hoping the technology (if not the car itself) makes its way elsewhere (and that Mitsubishi makes slots that can accommodate other iPod models).
Wouldn't it be cool if Macs had slots like this?
