I'm in this group.

What's surprising (or not) is that of the 12% of homes with a Mac, less than 2% are Mac-exclusive.

The 2% figure is extrapolated from NPD's less direct assessment:

[A]pproximately 12 percent of all U.S. computer owning households own an Apple computer, up from 9 percent in 2008. While Apple ownership is growing, those households are decidedly in favor of mixed system environments. Of those 12 percent, nearly 85 percent also own a Windows-based PC.

I only own a mac. But the schoenrock owns a PC. he sux.

My home has three Macs and no PCs, unless you count a rarely-used virtual machine on one of the Macs. I also have a Mac at work. I'm a hardcore fanboy. :/

me and my sister are mac only households..

 

my parents use macs now, but still have an old PC kicking around for a few menial tasks

Maybe it just means Apple's switch campaign was successful, and people just didn't get rid of their old PCs.
