Ipods are not neccasarily evil, but that all depends on how you use it. I'm sure the same could be said for television, alcohol, tobacco, and the sorts as these seem to ensalve so many people. I mean, if you listen to your tunes for enjoyment of life or a good song: go for it. There's certainly nothing wrong with that. But once anything, and I mean anything, comes across that line to consume your life, that's a real issue.
If you cant survive life without your Ipod, then there's certainly a problem. If you chose to avoid life's problems, create your own prison, or just cannot exist without tunes pumping through your ears, that's the problem. Granted I know the reason to listen to tunes is to escape but to be in constant use for an eternal getaway really should make anyone wonder.
