Apple introduced the Generation 2 iPod shuffle in September 2006 and advertised it as “the most wearable iPod ever,” due to a clip on the back that could easily attach the iPod shuffle to clothing.
The iPod shuffle was so small that the 30-pin iPod dock could not be used to charge or transfer music and data to the device. Instead, the Generation 2 iPod shuffle used this iPod shuffle Dock. The dock connected to a computer with an attached USB cable and data transfer and recharging was handled through the dock’s headphone jack.
The iPod shuffle Dock was only available in white, even though the iPod shuffle was available in several colors [silver, two variations of pink, orange, green, and blue; and turquoise, lavender, mint green, and (PRODUCT)RED].
Replacing the “squat” design of the Generation 3, the iPod nano Generation 4 returned to a “skinny” design similar to its predecessors. The new wraparound curved aluminum and glass case was offered in an unprecedented nine colors: silver, black, purple, blue, green, yellow, orange, pink, and (PRODUCT) RED Special Edition. The display was a wide-format 2-inch (diagonal) color LCD display at 320×240.
The iPod nano Generation 4 used either 8 GB or 16 GB of flash memory, capable of storing 2000 or 4000 songs, 7000 or 14,000 photos, and 8 hours or 16 hours of video. All colors were offered for both capacities.
The iPod nano Generation 4 features included an accelerometer (automatically switched to “Cover Flow” navigation in landscape orientation), games and videos only played in landscape, a new Genius feature to dynamically create playlists, and shake-to-shuffle for songs. Accessibility options were added including larger text and spoken menu items. It also included Nike+iPod support, FM radio tagging (using the Apple Radio Remote), support for audio crossfade, and games including Maze, Klondike, and Vortex.
The iPod touch Generation 2 is similar in features to the iPhone 3G, but lacks phone features, mobile phone networking, GPS, and a camera. While the back of the iPod touch Generation 2 is made of stainless steel (instead of plastic), its shape is similar to the iPhone 3G.
The iPod touch Generation 2 featured a multi-touch 3.5-inch display with 320×480 resolution, an accelerometer, ambient light sensor, Wi-Fi (802.11b/g), and 8, 16, or 32 GB of flash memory.
Compared to the original iPod touch, the Generation 2 model adds external volume controls on the left side of the device, an integrated speaker, external microphone (supported via the Apple Earphones with Remote and Mic), support for the Nike+iPod Sport Kit, a Genius feature to dynamically create playlists, and shaking the device to shuffle songs.
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.
The iPod shuffle Generation 3 was released in two stages. The initial release came in black and silver, and a later release added blue, green, pink, and an all-stainless-steel “Special Edition.”
The design of the iPod shuffle Generation 3 was considered somewhat controversial because it had no external screen or controls. The three controls—volume up, volume down, and “action”—are all on the earphone cable. VoiceOver technology, accessed using the “action” control, spoke song information.
This example is an unopened stainless steel Special Edition. It was only offered in a 4 GB capacity, and was only available at Apple Stores.
The iPod nano Generation 6 was a major design change from previous iPod nano models. This iPod nano came in silver, graphite, blue, green, orange, pink, and (PRODUCT) RED Special Edition. Its design was a square aluminum and glass case with a clip on the back and a 1.54-inch Multitouch screen.
Although its interface looks similar to iOS, it cannot run iOS applications or games compatible with previous iPod models. Its features include a pedometer, FM radio with live pause, Nike+iPod functions, VoiceOver, and Shake to Shuffle.
This version of the iPod shuffle Generation 2 was updated to include five colors: silver (original), orange, green, blue, and pink. Also, this revision switch from the old-style “cap” earbuds to the current, more streamlined design. The case of this iPod shuffle features a clip that allows you to easily attach it to clothing.
This iPod shuffle’s design greatly differs from the original iPod shuffle that looked and functioned similarly to a flash drive. To charge this iPod shuffle and load it with up to 240 songs, it sits in a very small USB base with a protruding 3.5mm jack that uses the audio jack to transfer data and charging power.
The iPod shuffle is the only set of iPod models with no display.
