Part of the point of the article is that it would not really add another resolution that devs would have to account for. A 7.85" iPad could have the exact same resolution as a non-retina 9.7" iPad and still have the same pixel density as the iPhone. This would result in UI elements that would be no smaller than normal for the iPhone, making it relatively easy for existing iPad apps to run with no modification.

Can you walk us through the math you did to arrive at the following conclusion? A 7.85" iPad could have the exact same resolution as a non-retina 9.7" iPad and still have the same pixel density as the iPhone.

  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...

The article focused on resolution, but with all of Apple's flagship mobile offerings bearing retina displays, I consider it a requirement that any new device is retina. I didn't make it clear, but I understand the author's talking about logical resolution. I'm wondering if the iPad (1024x768) resolution scaled to 7" would effectively be Retina based on Apple's definitions. He scaled it by a factor of the iPhone's logical PPI (not the Retina pixel density). If the resolution was scaled by the required PPI to create a retina display (at ~7"), would a 1024x768 display still work out to a physical size of approximately 7"?
