Many people using Android big smartphones, do not bother getting a tablet too. The main reason seems to be that the functionality is overlapping and the screen advantage isn't that important. I wonder, how would iPad Mini owners think after getting a bigger 4,7" screen iPhone? Would they still use both devices or will the difference be so small that the iPad Mini will be neglected? I believe this is one of the risks for Apple, especially since no one else really sells so many tablets..
