Twelve percent of households own Apple computers, up from 8 percent in 2008, according to the NPD Group’s 2009 Household Penetration Study, based on the results of more than 2,300 online panelists. More than 8 out of 10 (85 percent) of these households also own a PC and 66 percent of them own three or more computers, more than twice the amount of PC households who own the same amount. No surprise considering the Apple tax and the fact that being an individual is pretty expensive these days, the average Apple owner is better off than most consumers. While 21 percent of all consumers make $100,000 or more, 36 percent of Apple's owners make over that amount.
“With a higher household income, though, it’s not a surprise that those consumers are making more electronics purchases,” Baker said. “The average Apple household owns 48 CE devices whereas the average computer household owns about 24.”
As you can see above, the difference is pretty overwhelming.
