Comparing disc brake pad life to V brake pad life is pretty reasonable, they're actually pretty close.
Wow, I really like your input. The pads are warn down to about the thickness of paper, so I believe that it would be prudent to replace them. I definitely feel lucky that I checked them, as one more ride and I would think that they would have gone to the metal to metal stage.
