Imagine the scenario where your name server crashes or is victim to some DoS 
attack, but httpd keeps running fine.  In this case, there would be some 
benefit to having a secondary name server out there.  Sean already mentioned 
a mail delivery failure that could occur if MX records were not available at 
all times.

There are many registrars that will provide secondary (and even primary) DNS 
services at no extra charge.  Gandi.net is one of those.
