The iPod is far more versatile than most people think. Not only can it store and play thousands of songs, it can also serve as a portable hard drive (after all, once you get past the pleasing exterior, that’s essentially what it is).
What benefit is this to you? The iPod can be a handy way to take your computer with you, sans laptop. If you transfer your personal settings to the iPod, you make any computer feel like your computer. And when trouble strikes, a properly configured iPod can put a cranky Mac back on its feet.
