A similar survey conducted last year by the NPD Group listed Mac ownership as 8%.
What really interested me, however, is that the NPD survey found that 85% of the Mac owners also own a Windows PC. Mac owners are also far more likely to have multiple computers in the house. Two thirds of Mac owners have three or more computers in the home, while only 29% of PC owners have two or more PCs.
NPD concludes that Mac owners not only own more computers than the norm, they also own more types of consumer electronics -- the average Apple household owns 48 consumer electronics devices compared to 24 in the average computer household.
