With the nation going digital, it was just a matter of time before mobile digital media players hit the market. In October 2001, Apple unleased its brand of iPod MP3 players on the market, beginning with the iPod Classic. Later, iPod models like the iPod Mini, the iPod Photo, the iPod Shuffle, the iPod Nano and the iPod Touch would enter the scene. The Nano iPod proved to be the most enduring model to date, effectively replacing the Mini. People who bought a new Nano could use Apple's intuitive iTunes software to legally download and transfer music from their computers to their devices. According to the most recent statistics, over 220 million iPods have been sold worldwide, making it the #1 selling digital music player in history.

The initial criticism of the Nano iPod was its faulty LCD screen. Within days of owning the product, some users reported that the screen was so easily scratched they couldn't even read the song titles. Even something as soft as a micro-fiber cloth was known to damage the delicate screens. Even though "less than 1%" of all devices suffered this problem, Apple agreed to replace iPod Nanos with cracked screens. Nevertheless, a class action lawsuit was filed and is in the process of wrapping up now — a step, which many say, could have been prevented if Apple had just offered full refunds on the Nanotechnology products, rather than charging restocking fees and keeping a short return policy period of 14 days.

Another criticism of the Nano iPod (and other models) is that the devices do not always live up to their advertised battery life. For instance, the 30 GB iPod's "14 hours of music playback" is, on average, only 8 hours. A series of 2003 class action lawsuits for "false advertising" won a number of individuals a $50 store credit or free battery replacements. The www.macintouch.com website reported "an average failure rate of 13.7%" for the iPods, noting that they were surprisingly fragile. In 2005, a class action law suit was filed for the defective screens, which scratched very easily, marking the Nano MP3 players useless. Apple solved this problem by issuing protective sleeves.

Despite its brushes with consumer dissatisfaction and lawsuits, the Nano iPod remains the top-selling portable music device in the world. The new Nano (Fifth Generation model) brings a lot of exciting Nano electronics' features to the table. This is the first iPod to hold FM Radio that can be tagged, paused and rewound. It is also the first to have a video camera (640 x 480) and allow one-click Youtube uploads. Purchasers of these new iPod Nanos will also find built-in speakers, voice-activated shuffle, a pedometer and a voice recorder. One thing people have been complaining about is the fact that this product still does not have a camera built-in! Even so, for 8 GB Nanos at $150 and 16 GB Nanos at $180, there are a lot of functions for such a small and affordable device.
