My 7 year old daughter used to use my iPad3 before she moved out with her mother so now I'm looking at a cheaper alternative as a Xmas present ,I've looked at nexus 7 ,kindle fire hd and galaxy tab 3 ,I think she would like it to have a camera as she used to play with it on my iPad ,Any advise on which one is the better choice it will be used mostly for apps and camera and watching cartoons ,thanks
