Given that the author self identifies on his blog as a twenty-something I'm wondering if he's old enough to have ever really had to lift IE v. 4-7.
IE was a vast pile of shit for about a decade. It was pile of shit so high that Microsoft took out ads saying in so many words that its latest version "doesnt suck, honest". I tore my hair out for years over IE bugs. Fucking kids these days. Mobile Safari might not be as magical as you would desire but it is not even in the same league as the virtual genocide/superfund/WMD that IE was.
