That phrase was not meant to be condescending. What I mean is that, while I can see why you'd want to share apps with your children, your adult spouse is their own person and can buy their own stuff. The article claims a 10-device limit may be too low for families, and I'm pointing out that two people remain two people even if they marry.

The article talks about a family of 4 with 4 macs, 4 iPads, 4 IPhones. We're well into the 1% territory there.

My Adult spouse an I have two iPhones and share an iPad. Sharing the one account (and thereby sharing applications) is great.
