IMac

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 four distinct forms. In its original form, the iMac G3, the iMac was gum-drop or egg-shaped with a CRT monitor, mainly enclosed by colored, translucent plastic. The second major revision, the iMac G4, moved to a design of a hemispherical base containing all the main components and an LCD monitor on a freely moving arm attached to the top of the base. 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 models, but is now thinner and uses anodized aluminum and black-bordered glass for its case.
