A couple years ago my dad had a stroke and he used my mom's iPad to play games and keep up with the news while he was in rehab. He had never been involved in the mobile market, and the only video games he was familiar with were some PC games and the game consoles I had. He didn't understand, especially in the condition he was at the time, that he was spending real life currency on extra lives in Toy Blast. He thought it was a virtual currency you got from playing levels. He ended up spending around $30, and Apple actually ended up refunding us the money when we told them what happened, but my point is there's more to the story than parents giving kids access to their credit cards.
