Opacity is a great example of why vendor prefixes are important. Opacity 
was implemented differently in each experimental implementation before the 
specification was written, and if the UAs had all use 'opacity' as the 
property name, the CSS working group would have been unable to take the 
experience of those implementations into account in designing the real 
feature. (Or, would have been forced to call it something else.)
