It seems to me that in discussions of NoSQL vs relational databases, one of the main arguments that comes up regarding ease of design and maintenance is "you can just use an ORM". But I see major disadvantage after major disadvantage of using an ORM, and there seems to be some overlap with the disadvantages of NoSQL (by which I am primarily referring to document-oriented databases). I really can't tell, once you factor these disadvantages in, what comes out on top.
