For the average Joe who is downloading porn, not a lot, but for data heavy industries it would have enormous benefits. The health sector would become futuristic with surgeons able to perform operations via robotics in real time on a patient in country Queensland, while sitting in his surgery in Sydney. This isn't science fiction, it just currently lacks the infrastructure to make it viable becuase of severe lag time. The same could be applied to education with country students having access to proper broadband speeds. The economic savings alone with this application would be enormous, and that is before some smart cookie stars thinking up new and wonderful ways to utilise these speeds.
