iMac is a family 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 debut in August 1998, and has evolved through seven distinct forms.In its original form, the iMac G3 had a gumdrop 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.
MacBook family were initially housed in designs similar to the iBook and PowerBook lines which preceded them, now making use of a unibody aluminum construction first introduced with the MacBook Air. This new construction also has a black plastic keyboard that was first used on the MacBook Air, which itself was inspired by the sunken keyboard of the original polycarbonate MacBooks. The now standardized keyboard brings congruity to the MacBook line, with black keys on a metallic aluminum body.
iPhone is a line of touchscreen-based smartphones designed and marketed by Apple Inc. It is considered to be one of the most important and innovative inventions of the 21st century. All generations of the iPhone use Apple's iOS mobile operating system software.
