Good point. It's not fair to associate Napster with slow download speeds. I would have loved to see how Napster evolved with broadband. Tragic they were shutdown.
In countries such as Sweden that was already the case. I never downloaded anything on napster in 56k-speed unless I was really desperate. Broadband was common enough that limiting yourself to high-speed downloads didn't limit the supply, which was kind of obvious considering that those with broadband typically had many orders of magnitude larger libraries :p
