Sorry, and it pains me to say it as I'm the patriarch of an OS X family, but: Kids. Their first exposure to computers will be at home. And it'll therefore likely be Windows. My kids don't know Windows, they know OS X and iOS. Sometimes, after they've visited friends, they comment that they played on a computer that "looked weird", but they've never had a problem adapting. It's that last bit that seems to suggest a "who cares what the OS is, kids don't care" idea. In my view, though, it really doesn't. Kids aren't known to have a higher order of executive function. They'll generally just use whatever the trusted adults in their lives use. Those trusted adults should be exposing kids to all the options, so that the kids are better prepared to make decisions when their executive function skills catch up.
