Let’s get one thing straight: You can’t go wrong by buying an iPod. Any iPod. But that’s not to say the decisions between which iPod to buy aren’t hard. In fact, it can be downright tough. The tiny iPod shuffle is awesome for working out, but it lacks a screen. The iPod nano has a screen but lacks applications. The iPod touch has applications but might be too bulky for working out and may lack storage space. The iPod classic has mega storage but no touchscreen joy. For the casual buyer, the choices are enough to drive a person batty.
