Wouldnt anyone would want a backpack that do it all. O'Neill's H2 doesnt do everything you want, but it does control an ipod, charge a gadget, and answer cell phone. It has solar panels on the back pack to charge an iPod, mobile phone or Bluetooth module via a USB recharging system. For hands-free calling, a built-in microphone is placed in the shoulder strap and headphone jack is on the chest pocket. When the user receives a call, the iPod transmission is automatically interrupted, pausing the music until the call ends.
