Is Eventual Consistency Useful?

As a continuation to The NoSQL Partition Tolerance Myth, Jeff Darcy:

Every once in a while, somebody comes up with the “new” idea that eventually consistent systems (or AP in CAP terminology) are useless. Of course, it’s not really new at all; the SQL RDBMS neanderthals have been making this claim-without-proof ever since NoSQL databases brought other models back into the spotlight. In the usual formulation, banks must have immediate consistency and would never rely on resolving conflicts after the fact … except that they do and have for centuries.
