The iPod Generation 2 was similar to the original iPod in design, but the moving scroll wheel was replaced by a stationary touch-sensitive scroll wheel. In addition, the FireWire port gained a cover. The top of the iPod design also changed to allow the buttons to be surrounded by stainless steel cutouts instead of the plastic top used in the original iPod. Accessories were also added including a wired remote control, a thinner Firewire cable, and a carrying case.
The iPod Generation 2 was offered in 10 GB and 20 GB models and also added Windows compatibility.
Other than the increased hard drive sizes that allowed the iPod to hold up to 4,000 songs in the 20 GB model, the other specifications were the same as the original iPod: a 60-mW amplifier, a FireWire port, and a standard 3.5-mm headphone jack, and a 2-inch black and white backlit LCD display, and a 10-hour battery.
The iPod Generation 4 shipped with a 20 or 40 GB hard drive and was the first full-size iPod to use the Click Wheel that was introduced with the iPod mini.
This example features a factory-etched Tivo logo. This etching option was offered by Apple for corporate gifts or promotions. In this case, I was a member of Tivo’s “Tivo Rewards” program that included a credit card that accrued points that could be redeemed for various rewards, including this etched iPod.
The iPod U2 Special Edition is a fourth generation iPod with a black front case (instead of white) and a red Click Wheel. On the back of the iPod U2 Special Edition, autographs of all four members of the band U2 are etched along with their printed names: Bono, The Edge, Adam Clayton, and Larry Mullen Jr.
This is the first of three iPod U2 Special Edition devices. The second version was based upon the iPod Color (iPod with Color Display), while the third versions were based upon the iPod Fifth Generation (iPod Video) and iPod Fifth Generation Enhanced. All models feature the same custom colors and engraved autographs.
The iPod U2 Special Edition (Generation 4) shipped with a poster and $50-off coupon for the complete U2 downloadable box set.
I purchased my version of this iPod from a co-worker, and I do not have the original box, poster, coupon, or earbuds.
