I am looking into purchasing an iPad for my 2 year old daughter, but it will be used by my wife and myself as well. I can't decide between the mini retina iPad or the iPad air. My child will be using it for children activities and my wife and I will use it for surfing the web, occasionally Ill use it for my school. If you've have a child that young and have gotten an iPad for them and yourself which size have you picked and would you suggest?
