It's a different approach based on age, too - the parental controls Apple provides are great for a toddler on an iPad, and may even work into elementary school... but not forever. You can't hide kids from reality, no matter what you take away. I knew too much and more by age 8 and we didn't even have the internet. When our son gets to be 6 or 7 we'll probably have to start explaining the concept of porn and online bad actors, and that's depressing, but it's the world we live in.
