According to “2009 Household Penetration Study,” approximately 12% of U.S. computer-owning households have an Apple computer, up from 9% in last year's study. But of these Mac-owning households, nearly 85% of them also own at least one Windows PC. “Multiple computer ownership is a common thread in Apple computer households, with 66 percent of households owning three or more computers, compared to just 29 percent of Windows PC households. Apple owning households are decidedly more mobile as well, with 72 percent of them owning a notebook, whereas only 50 percent of households that have a Windows PC own a notebook,” revealed NPD.
