This author's insightful article is easily destroyed by his sheer arrogance and the tone at which he makes an inappropriate statement, attacking the majority of the users.
"The Retina MacBook Pro is still very much a luxury item, but we've had a Retina iPad for almost a year and the iPhone 4 for two and half years. And yet, the internet is still having a hard time adopting."
Because the rest of the internet aren't Apple fanboys and unfortunately, that's the massive majority.
The ideal solution - Don't give a shit about Retina displays, because these tiny fraction of Retina users are already 'used to' looking at normal websites in a pixelated fashion. They'll get used to your website too.
Until the retina resolution is adopted by the rest of the Internet, you have my zero fucks.
