One of the great joys about a device like the iPod is that it doesn't just do music. It does videos. It does text. It does games. It does pictures. You can use it as a portable hard drive. With the proper hardware, it can do radio and it can record voice memos and do even more. The device is so flexible, one is constantly finding new ways the Apple engineers have thought of to break out of the MP3-player box and give more power to both developers and end users. The iPod's Notes feature is a great example of this power.
