Do you actually believe that the magical "retina" mark just coincidentally happened to be 2x Apple's original resolutions? How convenient!

It’s a petty good approximate term

It's a marketing term that the stupid embrace. Is a 64Kbps mp3 "eardrum audio" in a standard room with a fan? Is 128Kbps eardrum audio on a crummy mp3 player?

That was an uninformed rant on your part

What was uninformed about it? Desperately curious to hear what.
