The iMac is a desktop computer designed and built by Apple Inc. It has been a cornerstone of Apple's Macintosh line of personal computers since its introduction in 1998, and has evolved through three distinct forms, all adhering to an "all-in-one" design ethos. The machine enjoys a relatively high profile in popular culture due to its distinctive aesthetics and Apple's successful marketing. The new 24" Core 2 Duo iMacs received CNET's "Must-have desktop" in their Top 10 Holiday Gift Picks.
