You will need these and normal ND filters when you want to or need to diminish high contrasts/enormous DR in a single shot, in order to use large apertures in bright conditions (for DoF control), and in order to use long shutter times in too bright conditions (f.e., for shooting flowing water in an attempt to make it look like it flows).
So yes, I do use them in those cases, and just like popo I have a Cokin system, actually, the Z-Pro, with a bunch of grad filters etc. I do find that even the standard dense grad and ND filters (1, 2 and 3 stops) are often not enough for the desired effect, not even combined. You may want to think about a 10-stop filter if you can get one <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='

I sold my Z-pro grads recently. Hadn't used them for years. I simply bracket landscapes now, taking one a couple of stops below normal, and then blend in the darker one manually. It gives much more control than using a graduated filter. Of course in principle there might be situations in which, because of movement, you want it all in one exposure. But I haven't encountered this except very very rarely; and that kind of photography is not usually one in which you want to set up graduated filters precisely!
Of course a very dark plain ND can be useful for long shutter speeds: better to get a good multicoated glass screw in one, rather than a resin...
