I am thinking about using a used iTouch for my 9 year old daughter for Christmas. Don't want to buy a new one since she still loses stuff! She plays with her dad's Android phone all of the time and loves the aps on it. I am assuming that you can put aps on the iTouch? If so, is there a certain generation I should stay away from (I get that newer is better but I don't want to spend a ton of money). Thanks for your input!
