As amateur pornographers, we can appreciate the fact that a SD or CompactFlash card doesn't hold enough pictures to last through an entire day of shooting. Good thing there's this Tripper Light from Aska Corp.
It's got a six-in-one card reader with a built-in 20GB hard disk to unload pictures to. That means all you have to do is stick in your card, hit copy, and you're back in business.
This one's Japan only, but you should be able to find similar ones for sale here.
