Uh, if they don’t use it then the cost/benefit ratio is even more balanced over to the cost. The point is that the cost was never consulted in the first place when the benefit was sought.
I'm responding to the statement that GP made which was that to someone who never used GOOG-411, the cost-benefit ratio is further into the cost category [compared to someone who did use GOOG-411]. This would imply that there is some cost to someone who never used the service, hence my question.
