I'm a Mac On and Off for Several Years Apple Inc. Has Been

I'm a Mac
On and off for several years Apple Inc. has been running its "I'm a Mac" advertising campaign. In the ads, seen on television and on the Internet, actors play the roles of a Mac and a Windows PC. The actor that plays the PC, often known as the PC guy, John Hodgeman, is portrayed as a nerd, while the Mac guy, played by Justin Long, is (of course) the "cool" guy. The ads tout the many advantages of the Macintosh operating system, ranging from its ease of use to its freedom from the many viruses that plague Windows-based PCs. For example, in one ad the PC guy tapes a camera to his head to make a video only to be reminded that all Macs come with a built-in camera. In another the PC guy sings a country song bemoaning the problems of the Windows operating system.
