Fair enough then, I've got the wrong end of the stick. I must admit, I didn't really think pure apple households were at all common.
if you've heavily invested in Apple media, the benefits to an Apple device would probably outweigh any individual feature wins of the Nexus 7.
if you're more of a casual Apple household, meaning just hardware and no media, the Nexus 7 is likely a fine choice.
I think a lot of it is people replacing older PCs with new Mac laptops, picking up the AppleTV because it is so cheap then finally buying an iPad as more of a curiosity.
A lot of them didn't really pay much attention to the competition because they weren't serious, considered choices.
