High-pixel density in your hand
Incredible high-resolution screens are no longer the stuff of top-of-the-line desktop monitors. After a few notable tablets launched this year, supersharp screens quickly became the norm for handheld devices. And it will only get better.
From the debut of the Retina Display on the iPad in March to the 10-inch Nexus 10's screen, sporting a resolution so high it was previously only seen on 30-inch monitors, 2012 marked the year that tablets got serious about their screen quality.
Amazon, Asus, and Barnes & Noble also brought impressive tablet screens to the mainstream and enthusiast alike, giving everyone a chance to experience high pixel density; now there's no going back. Any tablet manufacturer worth its weight in pixels will be forced to heavily consider a high-resolution screen if it hopes to succeed in 2013 -- or at least offer a significant discount for what will soon be considered a subpar visual experience.
