Oxygen Audio's O'Car has a RDS radio tuner and a 4x55W amp, but the magic happens when you strap in your iPhone. The rotating mount charges your phone and holds it horizontally or vertically, letting you play tunes through the iPod app or Pandora radio, put your iPhone to work as a GPS navigator, or make hands-free calls over your car's speakers. Or play Infinity Blade while you're in bumper to bumper traffic.
Aside from radio, the O'Car doesn't do much on its own, so hopefully it won't be too pricey when it's officially debuted at CES in January. All I know is that I wouldn't shed a tear if I had to retire that stack of half decade old CD-Rs that are shoved in my car's every nook and cranny. [O'Car via Wired]
