Re: Tablet question.
We got my oldest (10) a Kindle Fire HD for Christmas. We got him the 7" version. He loves it. If you go Kindle my advice is to pay a little extra for no advertisements. I don't like how it is so easily integrated into the Amazon shopping system. So if you don't trust him. Look elsewhere.
