The iPod Mini brought a palette of vibrant colors to Apple Computers' lineup of music players. The Mini debuted in January 2004 and quickly became a top seller. A February 2005 upgrade added a 6GB model and boosted battery life to as much as 18 hours.
When Apple unveiled the iPod Nano in September 2005, it hailed the product's small size: The music player weighs 1.5 ounces and is a quarter-inch thick.
