 The AirPort Extreme (802.11g) card was discontinued in January 2009.As 802.11g began to come standard on all notebook models, Apple phased out the user-installable designs in their notebooks, iMacs and Mac Minis by mid-2005, moving to an integrated design.AirPort continued to be an option, either installed at purchase or later, on the Power Mac G5 and the Mac Pro.
