Display
When Retina first hit the scene in the iPhone 4, its new display was like nothing before. But, BlackBerry, HTC and others have caught up or even surpassed Apple's pixel-dense display. Now we can include the Galaxy S4 in that list. Its 5-inch Super AMOLED display puts out an eye-popping 1,920-x-1,080 resolution. You read that right. The Galaxy S4's monitor crams the same number of pixels into a screen 5 inches across as does a 27-inch desktop display. Using Sven's trusty pixel-per-inch calculator, the math on Galaxy S4's display resolution rounds off to an impressive 441 ppi, an industry high. By comparison, the 4-inch Retina panel on the iPhone 5 puts out 1,136-x-640, or 326 ppi. And with pixels, more is better. Galaxy S4 protects its panel with Gorilla Glass 3, Corning's latest; the iPhone 5 resists fingerprints. Display advantage goes to Samsung.
