Analysts say the new low-price Mac mini could incite more Windows users who own iPods to buy their first Mac, providing a boost to the so called “halo effect.” Charles Wolf, an analyst at Needham & Co., said that he now estimates 11 percent of Windows iPod users may switch to a Mac now that the Mac mini is coming to market. Before that, he assumed the rate would be closer to 4 percent. “The iPods only failure has been its inability to stimulate meaningful purchases of Macintoshes,” Wolf said. “We believe the Mac Mini will increase the percentage of iPod-toting Windows users who purchase a Mac by almost threefold.”
