I am using it . Its battery is amazing . RAM is bit slow . Its internal memory is 11.5 GB ( memory limit for apps ) . Back camera is just amazing . Front is not bad but not so good as well . If u have any questions about it , please ask me.iPad 3 is fine only on some games ( It's fine playing my favourite games) , a bit lag sometimes but not much with iOS 9.2 and above. Still on good speed on 3G but I reckon should use this if you're okay having wifi.but more expansive in india.any question ask me.
