I say get the Ipod -- if you're a perfectionist like I am with my CDs, having an ipod means I'm not scratching my CDs/wearing them out/whatever. Plus its small and easy to carry. Also if (like me) you can never decide what you want to listen to before you leave the house (and hence which cd you should take with you) and ipod is great -- whenever you change your mood you can change your music!
hehe I heart my ipod
