“but the vast majority of iPhone users are not children”

Just want to point out that while children might not use you're iPhone, one does use my wife's and used my iPod Touch as much as we do. Know, she's not placing phone calls on it, she got the same dozen-and-a-half or so apps just for her on both devices.

Granted, children aren't the direct target for the iPhone, but they are a secondary users of it. Or as is the case for my iPod touch, it's primarily for her. While I have all my apps on it, we have Playhouse Mickey, Caillou, and other TV shows as well as Mary Poppins, Dumbo and other G-rated movies for trips in the car. Not to mention the many alphabet, math and reading games for use in the restaurant while we're waiting for food or when mom and dad want to have a few minutes of quiet time after she's finished her meal.

My wife and I are the filter of what she views, hears, and accesses as much as humanly possible. The world being what it is, we can't control everything. Having said that, we appreciate Apple taking extra measures to help filter content. It's not their responsibility, but it sure helps. For those who don't see the benefit of a company taking children into consideration, well then you simply must not have children. While there's nothing wrong with not having children, just don't be so quick to slam Apple for their efforts.
