Apple's "retina" displays? Pretty soon you won't have to, according to Intel slides published by Liliputing. The chipmaker believes devices with high pixel densities will wash ashore as early as next year, offering 220-300 PPI on virtually every display-bearing gadget in your arsenal. It's predicted that handheld devices with viewing distances of 12 to 16 inches will have a pixel density of about 300 PPI, which works out to 1280x800 on 5-inch smartphones and 2560x1440 on 10-inch tablets. For reference, the iPhone 4 and 4S have a resolution of 960x640 (326 PPI) and the third-gen iPad's screen is 2048x1536 (264 PPI).
