redesign interfaces and designs for the new displays: The sort of rich, data-dense information design espoused by Edward Tufte can now not only be made on the computer screen but also enjoyed on one. Regarding font choices, you not only need not choose a font optimized for rendering on screen, but should not. Fonts optimized for screen rendering look cheap on the retina MacBook Pro—sometimes downright cheesy—in the same way they do when printed in a glossy magazine. Detractors Raymond Soneira, president of DisplayMate Technologies, has challenged Apple's claim. He says that the physiology of the human retina is such that there must be at least 477 pixels per inch in a pixelated display for the pixels to become imperceptible to the human eye at a distance of . Astronomer and science blogger Phil Plait notes, however, that, "if you have [better than 20/20] eyesight, then at one foot away the iPhone 4S's pixels are resolved. The picture will look pixelated. If you have average eyesight [20/20 vision], the picture will look just fine... So in my opinion, what Jobs said was fine. Soneira, while technically correct, was being picky." The retinal neuroscientist Bryan Jones offers a similar analysis of more detail and comes to a similar conclusion: "I'd find Apple's claims stand up to what the human eye can perceive." Apple fan website CultOfMac hosts an article by John Brownlee who incorrectly stated that the resolution the human eye can discern at 12 inches is 900 PPI, concluding "Apple's Retina Displays are only about 33% of the way there." On the topic of 20/20 vision, Brownlee misrepresented visual acuity in the population saying "most research suggests that normal vision is actually much better than 20/20" when in truth the majority have worse than 20/20 vision, and the WHO considers average vision as 20/40. Brownlee also stated that people do not always view displays at a constant distance, and claimed a close-viewed display could no longer be classed as Retina. However, near visual acuity is usually poor due to presbyopia in nearly everyone over 40, such that decreasing reading distance can actually reduce perceivable resolution. Competitors The first smartphone following the iPhone 4 to ship with a display of a comparable pixel density was the Nokia E6, running Symbian Anna, with a resolution of 640 × 480 at a screen size of 62.5mm. This was an isolated case for the
