Depends on what you will be using it for the most. We are an "Apple" family. It comes down to quality for us. Six in the family home and we have 2 iPad minis, 1 iPad, 1 MacBook and 3 iPhones in house...oh and 2 iPod Touch. I think the iPad mini is functional enough for reading. The iPad is bigger and has been dropped (w/o a scratch). But it was dropped because of it being bigger, harder to hold at times.
That is my 2¢.
