So the html looks as god intended on mobile devices. It became necessary, because web pages squeezed to mobile sizes were looking terrible with all those sidebars bent and excessive padding and margins. So Apple (I believe it was them) made this workaround, by default your phone renders pages scaled, like it's a window to your desktop computer's maximized browser. Then it looked good. But what about pages that are responsive or just look good no matter the window size? That's the line that needs to be there.
