I have I pad mini 3, I like it very much and the interesting thing is that my 5year old daughter like it more than me, actually this is the gift from me to my daughter and she loves it, it is very user friendly also for kids.
I pad 3 is no doubt a best tablet from apple, ur kids can learn more with this I pad, it also have security featured or we can say child lick facility, so u can restrict the content which u want not to watch by ur child.camera and picture quality is excellent, multitasking and video shooting is fun with I pad 3
