I keep squinting at my new iPad, trying to see the pixels, but no dice. Luckily, Ignore the Code rounded up some microscope imagery of the new iPad's screen and compared them to other devices. Something that surprised me was the quality of the PlayBook's screen. But the density of the Retina Display is truly something you have to see for yourself in action -- it is magical.
Check out the images at Ignore the Code if you're interested in how those displays look so good.
