It's interesting that the nostalgia for "pixel-perfect design" comes from a company that seems to have been on a mission to remove pixels from the user's perception for the last 20 years.

First, Apple promoted skeuomorphism as the most visible difference from the pixelated look of Windows (OS X, 2001).

Secondly, they made pixel-perfect designs irrelevant by making a powerful, small handheld computer. It made the goals of pixel-perfect design futile and triggered the RWD trend instead (iPhone, 2007).

Thirdly, they successfully pushed Hi-DPI screens to the masses, which make the smallest elements on the screen too small for the naked eye to be seen. (Retina, 2010).

I say it with all due respect. These are absolutely brilliant achievements. Still, some "Yeah, thank us for killing pixels" would be in place.
