Bad Math: I had the same thoughts Kevin did when I saw the Napster Superbowl ad telling me to do the math.  "If you sign up when you are 15 years old. By the time your my age (30), you'll have spent $2,700 to not have your music collection in your physical possession." I buy singles on iTunes, but I still prefer to buy music in a physical form that allows me the ultimate portability over time.  Maybe ours is the last generation that cares about really owning our digital media. If this model takes off then I'll take it as one of the first signs that I'm "just getting old and don't understand".
