So the trick is that Apple tells App devs that the minimal tappable UI element at 44x44 points. - The original iPhone had a PPI of 163PPI - The original iPad had a PPI of 132PPI The 44x44 point recommendation was the same for the iPhone and iPad. So the minimal tappable element on the iPad happened to be physically bigger even though it was the same # of points. A 7.85" iPad happens to have a PPI of 163PPI. (same as original iPhone) So that means any UI element designed with a minimum of 44x44 points will still be as tappable on a 7.85" iPad as it was on the iPhone. If you see the PDF/actual-size file I linked in another comment, you'll see the UI elements on a 7.85" iPad are no smaller than elements on an iPhone. actual math here: http://www.appadvice.com/appnn/2012/03/apple-has-163-reasons-to-release-fabled-ipad-mini http://www.appadvice.com/appnn/2012/03/apple-has-163-reasons...
