I don't know if other OS can do this, but you can pin website, the sad part is, the tile is not pretty and most people don't know they can do this.
And honestly it is so painful to make pixel perfect website that works on major all three major web browsers. For example, Chrome include scrollbar in the dimensions when FF put the scrollbar outside. And FF still can't handle standard border radius CSS. Just painful. Not to mention SVG exploit on Chrome.
