According to MetaFacts 2006 Home PC Brand Profile Report, 46% of Apple's base is over the age of 55, compared with 25.2% of other platforms. The Home PC Brand Profile Report is "one of a series of summary reports on specific topics based on the results of MetaFacts' 2006 Technology User Profile (TUP) study, which reveal the changing patterns of technology adoption and use in American households and businesses."
