Click Here For Link Microsoft plans to begin running ads promoting its software products for Mac users, emphasizing the idea that Apple and Microsoft products can live in harmony, even on the same desktop. The ads, which will debut in Macintosh publications Saturday, will use a humorous approach to attempt to dispel the long-held belief of many computer users that Macs and PCs occupy separate and distinct parts of the technology universe. One of the ads shows a Mac and a PC sitting on adjacent lounge chairs beside a pool, engaged in a game of chess. Another shows the two computers watching movies together over boxes of Chinese takeout. A third shows them fishing together. The ads refer their audience to a Web site where Mac users can get a free 30-day trial of Office v.X.
