A maybe more importantly, a smaller iPad is needed to break into certain businesses who could use something bigger than an iPod, but portable than an iPad. For example, wait staff at a restaurant. iPods are too small, and an iPad is too big. Something in between is just the right size. I've also seen some cabs/shuttles using small Android tablets for GPS & dispatch. Here, the ideal size for something mounted is is between an iPad and an iPod. I could go on and on with ideas.
