For Christmas my oldest wants a Kindle Fire and my second oldest wants a tablet. Thinking of size 7" but wanted one that has the parental controls ~ I was looking at Nabi and Kurio but seems to young for him or too childish. But thinking of an android. I want to be able to control where he can go on it and keep him from areas that he should not go on it. He is ten years old and will use it for games, educational type stuff. Any ideas?
