The iPod isn't trying to go mass-market by exposing a focus group for a short time. It's trying to go mass-market by exposing a minority of vocal earlyvangelists and having them show people why it's useful. So far it's working really, really well. The question is just whether they can keep it up -- if the use cases continue to be interesting and compelling to, say, 10% of the population rather than just 1% of it. Still too early to tell.
