My son is asking for a 7" tablet for Christmas. We are an Apple household, but if I can save some money and go for either the Nexus 7 or Fire HD, I'm open to it. One of the main uses will be for him to take it to school to read books. I have Amazon Prime and the free book downloads is a very nice feature. Not to mention the Prime Videos. He'll also want to surf, play games, watch Youtube and movies. Anyone here have a Fire HD? Are you happy with it? Any regrets?
