Fairly straightforward question: when does apple reach market saturation with their ipod? I mean, sure there are only 2 million out there now, but they are really taking off now, and really, how many people can afford $300 mp3 players, no matter how cool they are? And how much turnover is there with current ipod owners? I have a 2g 20 gig, and I would love a 3g 20 gig, but that's a lot of cash to lay out. Even if my ipod were to break, I couldn't justify buying another one. Does apple only get one sale per customer every (insert uninterrupted lifespan of ipod here)? Which leads to the next question: what is apple cooking up next? Ipod was a pretty good stopgap, to keep revenues up while the g5 was getting worked out, but will apple now go back to just selling machines?
