the fact its got a stonking big screen and processor power gives it greater functionality alone. yes, does the same as the previous ipads, only better, faster and more efficiently in a big way. this is the very definition of functionality.
so yes, it does do a little more than a standard ios device. a little different? well, i did read the ios was slightly tweaked to account for the Pro.
or are you guys after a completely different functioning ios for each style mobile device? as it stands ios is ios. thats the point. it's the hardware that changes and boy, is the Pro certainly different than anything before, purely down to it's size, spec and additions.
