The iMac G4 was a computer that was produced by Apple from the beginning of 2002 to mid 2004. It replaced the aging iMac G3. The computer had a new design compared to older Macs.

The G4 had a 15-inch LCD which was mounted on an adjustable arm above a hemisphere containing a full-size, tray-loading optical drive and a sixteenth-generation CPU (the PPC 74xx-series). This LCD computer was known and sold as The New iMac, while existing egg-shaped iMac was renamed the "iMac G3" and continued to be sold for a few months. After the iMac G3 was discontinued, it was retroactively labeled iMac G4 to distinguish itself from the succeeding iMac G5.

The iMac G4 was sold with the "Apple Pro Keyboard" which would be later renamed the Apple Keyboard and an Apple Pro Mouse which would be later redesigned and named the Apple Mouse. Also, there was an option to buy the "Apple Pro Speakers", which were better quality than the internal speakers, which were low quality due to their size. Apple Pro Speakers had a unique, small adaptor and only worked on a select few macs (such as this one).

The iMac is a range of all-in-one Macintosh desktop computers designed and built by Apple Inc.. It has been the primary part of Apple's consumer desktop offerings since its introduction in 1998, and has evolved through five distinct forms.

In its original form, the iMac G3 had a gum-drop or egg-shaped look, with a CRT monitor, mainly enclosed by a colored, translucent plastic case, which was refreshed early on with a sleeker design notable for its slot-loaded optical drive. The second major revision, the iMac G4, moved the design to a hemispherical base containing all the main components and an LCD monitor on a freely moving arm attached to it. The third/fourth major revision, the iMac G5 and the Intel iMac placed all the components immediately behind the display, creating a slim unified design that tilts only up and down on a simple metal base. The current iMac shares the same form as the previous model, but is thinner and uses anodized aluminum and a glass panel over the entire front. It also adds an SDXC slot directly under the slot-loading SuperDrive. The newest version features quad-core Intel processors across the line, 1 (on 21.5″) or 2 (on 27″) Thunderbolt ports, and a FaceTime HD camera, features introduced on the early 2011 MacBook Pro updates.

Steven Paul "Steve" Jobs (/ˈdʒɒbz/; February 24, 1955 – October 5, 2011) was an American businessman, designer and inventor. He is best known as the co-founder, chairman, and chief executive officer of Apple Inc. Through Apple, he was widely recognized as a charismatic pioneer of the personal computer revolution and for his influential career in the computer and consumer electronics fields. Jobs also co-founded and served as chief executive of Pixar Animation Studios; he became a member of the board of directors of The Walt Disney Company in 2006, when Disney acquired Pixar.

In the late 1970s, Apple co-founder Steve Wozniak engineered one of the first commercially successful lines of personal computers, the Apple II series. Jobs was among the first to see the commercial potential of Xerox PARC's mouse-driven graphical user interface, which led to the creation of the Apple Lisa and, one year later, the Macintosh. During this period he also led efforts that would begin the desktop publishing revolution, notably through the introduction of the LaserWriter and the associated PageMaker software.
