The obvious advantage of GND over processing is it allows you to shoot star trails over a significantly brighter foreground.

(Not my shot, it's off OCAU)

No amount of bracketed shooting or HDR processing would bring out this level of detail.

That type of shot is still achievable with post-processing, without a GND.
Especially since the star trails is made up on small individual exposures.

You can just use masking to use one or more of the exposures for the foreground.

I agree with your thoughts about grad ND filters.

I used to think that all effects performed "in camera" were better than post processing, but a very talented pro graphics designer + hobbyist photographer friend of mine has thoroughly busted that idea for me.

Although my raw frames for landscapes are better than his (when I've compared them side-by-side), the magic that he pulls off on the computer is just stunning.

Murphy - are you sure that image you linked to was shot with a grad ND filter? If it was, you'd expect to see the star trails reduce in intensity as they approach the horizon (they don't), or you would expect to see a gradient across the taller buildings (there isn't).
