Aisle5Deals offers this 32GB Thumb Drive
for shipping ($0.69/GB). That's the lowest total price we could find for any such thumb drive, though we have seen non-finger-shaped drives of this capacity for less. This opposable digit drive is what separates us from common animals (note that we didn't
say "makes us better than", just "separates"). Deal ends January 19.
Alternative, darker, joke: Just remember not to put it in your severed-finger drawer or you'll never find it again.
