Gotta say I think iPod will always be "the" brand, much like my old AppleIIe or Laser or Commodore64 system. However, now when I'm looking for computers, I of course would not search for any of those terms.
iPods need to get to be a lot cheaper, or they will be beat by the NUVO's, the Dell's, the Nomads and others.
On the domain itself, start a forum... Yesterday.
If you need help getting a first forum up on there let me know, but this is the time that people would be on there talking if they're ever going to be (In the month til and month after X-Mas as kids and others are looking forward to getting them and then looking to talk about how cool they are for having them).
Now, low $xx, start up a base of maybe 150 a day and you have a completely separate game.
