do you think IPOD is necessary or luxury?

Well, so far I've managed to live my life without having one, so I guess I'd have to say it's a luxury. I have always kind of wondered if it would be worth buying, but I just never had the money to waste. I guess if I spent a lot of time doing activities where I wouldnt' have any other entertainment, I might think of it differently, but usually I'm either at home (where I have tv, computer, etc) or at work where I'm busy working, or with friends playing games or whatever, so I never really would have time to use an IPOD if I had one I think.
