It's simpler than that (Score 1)

My Dad, Grandfather, youger brother, friends, roomates, girlfriends all own iPods for one simple reason. They don't have to think to use it. Although PDA's do a lot more, the general public does not need that much. I benefit from wi-fi and email access in a PDA, but most people, who would have a hard time explaining what a POP server is, just don't care. All they want is one button to push to hear their music. Living on the edge, although has it's advantages, is not for the general population.
