Memory will always be cheaper than bandwidth and far more pervasive. It makes no sense to download something, then 10 minutes download it again. We already have pervasive non-downloadable streams - it's called radio. It's still popular, but has never completely displaced having your own collection. One of the killer uses of digital music is the ability to have a miles-long playlist for long road/plane trips. Downloadable streams cannot possibly service this market cheaper than a solid-state memory device. Wherever you have a market segment that needs two devices, the one that combines both always wins. So the future is an iPod that can stream if necessary - which we already have in the iPhone.
