Apple announces a $99 iPod and the world shrugs. Is there a market out there for cheaper iPods with no display that only plays songs in random order? And isn't part of the iPod appeal the size of its hard drive? What do I know? Smarter people than I have probably researched this and focus-grouped it into the ground. But one last question: if U2 helped launch the mega-deluxe iPod, will the smaller one get shilled by Smashmouth?
