Everyone wants one. They come in all sorts of shapes and sizes, colors and cases. Most let you listen to music, some allow you to watch video and a few are even wireless. They're one of the most popular consumer electronics products out there and a computer company named Apple is the current industry leader. We are of course referring to the mighty digital audio or MP3 player.

Since their introduction in the late '90s, digital audio players have become one of the run away successes of portable electronics. 2003 sales figures, according to the Consumer Electronics Association, were a staggering $556 million, which was a 171 percent increase over the previous year. More importantly, the CEA projects this revenue will grow by another 27 percent this year.
