Polycarbonate IMac
Alongside the MacBook Pro, the iMac Core Duo represents Apple's first computers to feature Intel processors instead of PowerPC processors, a transition that completed in November 2006. Since the introduction of the iMac Core Duo, other lines have followed, including the introduction of the Intel Core powered Mac mini on February 28, 2006, the MacBook consumer line of laptop computers on May 16, 2006, the Mac Pro on August 7, 2006, and the Xserve in November 2006, completing the Macintosh family transition to Intel processors.
In early February 2006, Apple confirmed reports of video display problems on the new Intel-based iMacs. When playing video on Apple's Front Row media browser, some 20-inch iMacs (those built-to-order with upgraded video cards) showed random horizontal lines, ghosting, video tearing and other problems. The problem was fixed with a software update.
In late 2006, Apple introduced a new version of the iMac which included a Core 2 Duo chip and a lower price. Apple added a new 24" model with a resolution of 1920 x 1200 (WUXGA), making it the first iMac to be able to display 1080p content in its full resolution, and a VESA Flat Display Mounting Interface. Except for the 17-inch 1.83 GHz processor model, this version also included an 802.11n draft card.
