Through the last year and a bit more, we have seen the laptop display resolution become fairly standardized at 1366 x 768 pixels, for most laptops, irrespective of the size of the screen. When this upgrade was made from 1280 x 720 pixels and 1024 x 768 pixels, it seemed like a big deal. But quite frankly, we have soldiered on with this for a bit too long.
But we must shower Apple with a generous dose of credit. Ever since the Cupertino giant started advertising the "Retina Display" on the newer generation of MacBooks and the other iDevices before that, the rivals in the expected craving to compete (or copy, depending on which camp in you are in), started making laptops with high-resolution screens. While the "Retina Display" varies across the different types of devices it comes on, the premise was simple - a screen with a pixel density that is so high that a user can't distinguish the individual pixels during normal use. To understand this, you need to look at the same content side-by-side, one on a standard 1366 x 768 pixel display and one on a high-resolution display.
