Personally, I'm not dropping more than $10/mo on any media service, and not likely to drop that much. Also, it takes me weeks to finish an audiobook--I dropped Audible because the credits piled up much faster than I cared to use them. Still, I can see how some people would appreciate this service in terms of sampling and browsing without committing to a purchase. Some people have a lot more time for audiobooks, too--long commutes and such, assuming you have data for this streaming service on your commute.
Would any of you use a service like this one? Is the cost too much?
