This is purely a thought exercise as I consider purchasing either the iPad Air or iPad Mini. I feel like there is a strong chance we will see a larger iPhone by next fall. As we move into 5 inch+ territory on mobile phones, I feel like having an iPad mini will become a bit redundant. I may not be thinking about this correctly, not having spent a significant amount of time with the Mini, but I feel like we would start to see an area where the usage for the devices start to seriously overlap. This seems to make a strong case for the full-size iPad still being a relevant product. I realize (if this actually happens) it's still a year off. Maybe someone that owns a larger non-iPhone and a mini can comment.
