Hi John,
Actually drag and drop itself as a technology is in my opinion mostly beautifull and not often useful. Some customers have said that they want it to rearrange user structures in trees, for example. But having been pointed to the calamity that might occur if you drop something accidentally on the wrong branch, they usually opt for more wizard-like operations
Having said that, I still like that DnD is part of Dojo, even if I rarely use it.
Cheers,
PS
