iPod shuffle (original, 512 MB, 2005)

The original iPod shuffle featured 512 MB or 1.0 GB of flash memory in a 3.3 by 0.98 by 0.33-inch case with an integrated USB connector. Like all iPod shuffle models, it lacked a display. The name of the iPod refers to its ability to shuffle among the 120 or 240 songs its capable of storing.

Like other iPod models, the shuffle can be used to store files other than music files, a feature that worked particularly well on the original shuffle with its integrated USB port.

The original iPod shuffle shipped with a white lanyard and a cap.

iPod nano Generation 5 (16 GB, blue, 2009)

The iPod nano Generation 5 was notable because of its impressive color choices. This model was available in nine colors: (PRODUCT) RED Special Edition, pink, orange, yellow, green, blue, purple, silver, and black. The finish for the generation 5 nano is glossy and the case is made of aluminum and glass. It was available with 8 GB or 16 GB of flash memory (2000 or 4000 songs).

This iPod nano also features a video camera with an integrated microphone and speaker that takes advantage of its high-quality 2.2″ TFT display (240×376, 204 ppi). The video quality is H.264 VGA 640×480 at 30 FPS with AAC audio, but it cannot take still photographs. This iPod also has a built-in FM Radio with “live pause,” allowing pause and rewind up to 15 minutes.

My example is blue, and I remember using it as a back-up/additional video camera that had surprisingly good audio for its size.
