easily noticeable between the iphone 5 and the htc one. not like the jump from 800x480 to 720p, but i wouldnt want to go lower in my next generation phone anymore. and why should i?
now apple, listen up, how about a "retina" screen for the macbook air, its quite ridiculous that my air has a way worse resolution at more than double the size than my phone.
Not to mention the current Air's display has poor color accuracy and terrible viewing angles.
