The iPad’s new Retina display is going to look fantastic. Reading text, for instance, is going to be like reading text in a real magazine, only brighter. This is great news for us, the readers, but not so good for the designers and publishers. Why not? Because many iPad magazines use bitmap images to make their pages. At normal resolution, this works out to perhaps 150-300kB per page, according to David Sleight of Stuntbox. When resized for the Retina display, that goes up to 2MB. Per page.
