LOVE the combo or real rock with white plastic tech. The istones, made by Brand Incubator of Japan come in Wabi or Sabi. USB 2.0 computer compatible. Fabulous inside or out.
Why keep your iPod in something boring when you can keep in a cool-looking rock? I'm not sure there's much more to say about this, other than this would look way cooler in your apartment than some lame docking station.
