What are the differences between the iPod shuffle 3rd Gen and the earlier iPod shuffle 2nd Gen?

Please note that all iPod models mentioned in this Q&A have been discontinued. The poorly received iPod shuffle 3rd Gen was replaced by the iPod shuffle 4th Gen on September 1, 2010.

The most notable difference between the iPod shuffle 3rd Gen models -- including the subsequently introduced "colors" iPod shuffle 3rd Gen line on September 9, 2009 -- and the earlier iPod shuffle 2nd Gen models is that the 3rd Gen eliminates the simple and straightforward controls from the body of the player.

Instead, the iPod shuffle 3rd Gen introduces an essentially three button controller -- volume up, volume down, and "action" (which varies depending on the number and duration of clicks) -- integrated with the headphone cable.

The iPod shuffle 3rd Gen also is the first iPod shuffle to support playlists -- groups of songs -- and introduces "VoiceOver" which speaks the title and artist of songs and playlists upon pressing the center "action" button (press and hold for the name of the song and the artist and press and hold until you hear a tone for the playlist).

These product images are not precisely to scale, but should provide a decent idea of the size difference. The second generation iPod shuffle is a tiny 1.07 inches tall, 1.62 inches wide, and 0.41 inches deep and the third generation iPod shuffle is an even smaller 1.8 inches tall, 0.7 inches wide, and 0.3 inches deep. Although it is not apparent from Apple's promotional shots above, the "clip" (with the Apple logo) on the iPod shuffle 3rd Gen has a mirrored finish.

Both use aluminum housings, but the second generation models were offered in a variety of colors, and the initial third generation models only were offered in silver or black. On September 9, 2009, however, Apple introduced new iPod shuffle 3rd Gen models in colors, which essentially are the same as the previous iPod shuffle 3rd Gen apart from the color options -- blue, green, and pink -- as new additions to the same black and silver colors offered previously and a new all stainless steel "Special Edition" as well.

Apple also eliminated the "dock" that shipped with the iPod shuffle 2nd Gen for connecting the device to a computer for the iPod shuffle 3rd Gen, and instead provides an extremely short headphone jack-to-USB cable for connectivity.

The iPod shuffle 2nd Gen was offered with 1 GB or 2 GB of storage, holding a reported 240 or 500 songs, respectively, and the iPod shuffle 3rd Gen originally was offered with 4 GB of storage, holding a reported 1000 songs. The "colors" iPod shuffle 3rd Gen models were available with 2 GB and 4 GB of storage, capable of holding 500 or 1000 songs, respectively.

The official estimated battery life of the iPod shuffle actually decreased by two hours -- 12 hours for the iPod shuffle 2nd Gen and just 10 hours for the iPod shuffle 3rd Gen. No iPod shuffle models have a screen, and consequently, only support music playback.

Interestingly, pricing was increased for the iPod shuffle 3rd Gen back to the US$79 price that the iPod shuffle 2nd Gen carried when it was introduced. The "colors" iPod shuffle 3rd Gen models, likewise, sell for US$79 for 4 GB of storage, but also sell for US$59 for 2 GB of storage and the stainless steel "Special Edition" -- only available direct from Apple and in a 4 GB capacity -- sells for US$99.
