College kids will always be college kids and rarely mature. No one is even remotely close to coming out with a high dollar product that combines all of the elements that go into an mp3 player as well as Apple, especially not style. Are you going to tell me that there will be a knockoff that 18-24 year olds are going to find more stylish and cool than the iPod?
You misunderstood -- or I didn't make myself clear -- on "mature market." A mature market doesn't have to do with the age of the consumer, but the number and types and price of units out there.
