why did the iPod become such a dominant device
back in the early 2000s when it cost $400-500?
I don't know why you say the iPod is a "dominant" device.
Sure it is successful, but it created a new market - tablets before it weren't really counting. It's easy to be "dominant" in a market that you created, but I'm also pretty sure that if you compare the number of iPad owners to the number of PC-owners, well, those numbers won't look so great.
What I'm trying to say here is that a LOT of people that would be interested in something like the iPad haven't bought one yet, and those people are much more in number than the current iPad users.
The pie is currently very small. It can be much bigger and everyone can have a slice ;)
