Used 1's and 0's..? O.o (Score 1)

How do you tell the difference between used 1's and 0's and brand spanking new 1's and 0's? In the digital world there is no such thing as used. What makes something used in the real world is wear and tear. That's why we have levels of use and pricing for used items. "Like New" and Abused All To Hell." I don't get it.
