To be held with one hand for long periods of time. People want the iPad mini more for the weight being so light that you don't always have to hold the device with two hands. If the iPad can continue to get lighter and thinner than I can see a lot of people who switched to the mini to the regular 9.7" iPad. I think weight is a big factor for the iPad that I think Apple would focus on for the iPad 5. That's why I am not getting the mini as the iPad 5 would be lighter and more portable as the mini.
