If you blow out the highlights, RAW will offer modest improvements in  
other areas when you attempt to patch of that lack of data at the very  
top. But for any other exposure issue, say underexposing, RAW offers  
(depending on the camera and settings) anywhere from a minor to a  
major amount of extra data, and can allow corrections of as much as  
three stops worth of exposure compensation. Thats a pretty big  
advantage; but only advantageous if you actually make adjustments to  
the highbit file.
