Not disagreeing with the value in the streaming offering, just saying why there is still a market for the rental-by-mail offering existing and why Netflix would still retain the offer (my guess is they probably rip the movies from the rentals and serve those in the streaming when licensing allows and rather than treat the Blurays/DVDs as just a cost of doing business, continue that operation).
