My younger brother's birthday is coming up. He's going to be 20. We were contemplating getting him an iPod or other MP3 player since he listens to so much music. But there's a problem... He's gone through close to a dozen iPods in the past 4-5 years. He doesn't replace them. He just... looses them. So we're thinking something cheap, but also something with at the very least 4 GB of storage. Any ideas?
