Welcome to the fast world of technology, where the just-released iPad Mini has already been expunged from our minds as we consider the future of the product. Thomas Verschoren thinks that slapping a larger-cut iPhone retina display into the Mini is a tricky proposition:
The downside: the iPad mini with a 326dpi display have a far better retina quality than the iPad at 264dpi. Selling the retina iPad as retina wouldn’t really be justifiable I think.
The difference between my 264 PPI iPad and my 326 PPI iPhone is only noticeable when I hold both very close to my face. I think that the display quality difference is small enough when the pixels are that dense that Apple can get away with selling both at the same time. It’s certainly more probable than the other scenario Verschoren proposes. Via The Beard.
