It's main advantage is automation, you can define a set of filters to be 
applied and have it automatically done when the render is finished. For 
example, you could have a logo automatically added by just adding a 
couple lines. If you want a higher resolution image, you can just render 
it at a higher resolution, and don't have to go through and re-process 
the image.
It also has information that other programs can't get, so there are some 
filters which would be impossible to make as a stand-alone program, the 
focal blur, depth, and normal filters for example. In future versions, 
you will be able to have per-object filters. Also, it has access to the 
full-precision color values, while other programs can only access the 
values after being clipped to a 0-1 range and usually reduced to 8 bits 
per component.
And finally, many post_process filters can be controlled by pigments, 
which would be much more difficult to do in an external program(you 
would have to render an image of the pigment separately).
