Announced in October 2001, the iPod represented Apple’s first strike into the digital music market. The iPod was a hard disk based digital music player that was smaller than most portable tape decks. Hard disk MP3 players had been in the marketplace for several years, but Apple distinguished the iPod from these players in several ways. The iPod could compete with both flash-based and hard disk based players: By using a 1.8″ hard disk, Apple was able to make the iPod smaller than most other hard disk MP3 players, small enough to go up against flash-based players, whose capacity was more than an order of magnitude less than the 5 GB available on the iPod. Apple believed the iPod represented the perfect compromise between size and storage capacity.

In addition to its remarkable size and capacity, the iPod also had impressive industrial design, something which had been distinctly missing from other hard disk players in the marketplace. Apple took a simple hardware interface consisting of five buttons and a scroll wheel, and combined it with a simple user-interface based on OS X’s column view. The iPod used FireWire as its I/O interface, as opposed to the then-prevalent USB 1.1. FireWire was much faster, and allowed for much faster transferring from Mac to iPod. The iPod was based on the PortalPlayer PP5002 System-on-a-chip, which itself had two embedded ARM7TDMI chips, operating at up to 90 MHz each. It had 32 MB of RAM as well, which was largely dedicated to “skip protection.”

Apple believed that it had a potent product, and priced it as such. The 5 GB iPod was priced at $399, a figure which was lambasted by the press as too high. If Apple had misjudged the market, it might have had another G4 Cube on its hands. As it turned out, Apple judged the marketplace very well, and the iPod, in its various incarnations, has sold better than anyone expected.

In March 2002, Apple added a 10 GB model to its iPod lineup, for $499. Several months later, in July 2002, Apple replaced the mechanical scroll wheel with a solid-state touch wheel, added a $499 20 GB model, and dropped the prices of the 5 and 10 GB models to $299 and $399, respectively (The 5 GB iPod kept its mechanical scroll wheel). In Addition, Apple for the first time made iPods available to Windows users. All models were discontinued in April 2003, with the released of the iPod (Dock Connector).

Notes

the 40 GB model was 0.69″ deep and weighed 0.39 lbs.

Announced in July 2004, the iPod (Click Wheel) was thinner, lighter, and cheaper than its predecessor. It also featured a redesigned hardware interface, based on the successful Click Wheel interface used for the iPod mini. Battery life was also dramatically improved, thanks to the use of a PortalPlayer PP5020 System-on-a-chip, which was much less power-hungry than the PP5002 used in previous players. The iPod (Click Wheel) was available in two models: a 20 GB model sold for $299, while a 40 GB model was available for $399. In February 2005, the 40 GB model was dropped, and the price of the 20 GB model was cut to $249.

Notes

The 30 and 40 GB models were 0.73″ deep and weight 0.39 lbs.

Announced in April 2003, the iPod (Dock Connector) updated both the look-and-feel and the feature set of the existing iPod. The iPod (Dock Connector) was thinner and lighter than the original iPod, and it introduced several new hardware features. The FireWire port was replaced by a “dock connector” which allowed the iPod to connect to either a Mac or PC, using either FireWire or USB 2.0. While less convenient for Mac users, the Dock Connector allowed the new iPods to be much more flexible in their I/O. It also allowed for any number of new third-party accessories, since the dock connector carried both sound and digital data.

The iPod (Dock Connector) had smoother angles than its predecessor, and moved the four buttons which had previously been arrayed around the scroll wheel to the top of the front face. These new buttons were backlit and solid state. Apple also added a variety of software feature enhancements to the new iPods, enhancements which were not made available on the older models.

The iPod (Dock Connector) was originally available in three sizes: a 10 GB model for $299, a $15 GB model for $399, and a 30GB model for $499. Both the 15 and 30 GB models came with a Dock. In September 2003, the hard drive capacity was increased on the two high-end models; the $399 now had 20 GB, and the $499 had 40 GB. In January 2004, the $299 model was increased to 15 GB. All models were discontinued in July 2004, with the release of the iPod (Click Wheel).

Introduced: January 2004

Terminated: February 2005

Announced in January 2004, the iPod mini was the height and width of a business card. Built around a 1″ 4 GB hard drive, the iPod mini raised the bar for portability in a hard disk music player. It was small enough to wear comfortably on an arm band, but large enough to hold nearly 1,000 songs. For its small size, Apple charged a premium: the 4 GB iPod mini was $249, only $50 less than a 15 GB full size iPod. Apple believed that its small size and consumer appeal would make up for its high price. As Apple hoped, iPod mini’s sold extremely well. So well, in fact, that demand vasty outstripped supply long into the summer months.

The iPod mini was available in five metalic colors: silver, gold, pink, blue and green. it was based around the PortalPlayer PP5020 System-on-a-chip, the same chip that would later power the iPod (Click Wheel). In order to fit everything in such a small package, Apple had to change the layout of the buttons from the exiting iPod design. All buttons were again made mechanical, and the four buttons which had previously been at the top of the front face were now placed underneath the scroll wheel. The result, which Apple called a “ClickWheel” allowed users to use the wheel as a touch-sensitive scroll wheel, or push on the four corners to click the buttons.

Announced in September 2005, The iPod nano represented a bold decision for Apple: to replace the best-sellingiPod mini, at the height of its market dominance, with a brand-new, significantly different iPod model. Whereas the mini had been based around a 1″ hard drive, the iPod nano was built around a 2 or 4 GB flash memory drive. The iPod nano’s look and feel was more aesthetically aligned with that of the iPod color than the mini’s had been. It also included a higher-resolution color screen, which, along with the remarkable decrease in physical size (half the thickness, 25% less wide), helped to justify the reduction in capacity. Although the nano held fewer songs per dollar than its predecessor, Apple sold the 2 and 4 GB nano models at the same price point as the previous 4 and 6 GB mini models: $199 and $249, respectively. Both models were available both in black and the traditional iPod white. In February 2006 a 1 GB model was added, priced at $149. All models were discontinued in September 2006, with the release of the iPod nano (Second Generation).
