I believe that usage-based pricing is valuable to the customer, but I see one problem for the vendor: If each use of the product is billed, this provides an incentive NOT to use the product. In other words, you actively drive usage down.
I'm not saying that I am against usage-based pricing or that it does not make sense, but especially in B2C markets, this might be a problem.
