A flash-based digital music player from Apple, introduced in 2005 with a color screen. Replacing the iPod Mini, the "nano" name suggests ultra-small, but the iPod shuffle is actually smaller. In 2008, with nine exterior colors, the 4th-generation nano was the most colorful iPod ever. It also added an accelerometer that automatically switches the screen from portrait to landscape mode. Shake the nano, and it switches to music shuffle mode.|
Video and FM in the Fifth Generation
Introduced in 2009, the 5th-generation nano added a video camera, FM radio and slightly larger screen (2.2" versus 2"). The camera is video only and not for stills. See iPod.
A Touch-Screen Sixth Generation - No More Video
In 2010, Apple introduced a different nano, replacing the rectangular unit and click wheel with a square touch screen. The video recording and playback were dropped.
The 6th-generation nano (middle) is a square touch screen available in seven case colors. No more click wheel and no more video. In this image, the tiny shuffle and touch flank the nano. (Image courtesy of Apple Inc.)
