It's also a potential hassle, where you can have IS-IS up and running, but 
have IP completely hosed. With OSPF this is harder as it actually runs 
over IP; no IP, no IGP adjacancy.

There is good reason why neither OSPF nor IS-IS rules the IGP world, they 
both have their advantages and disadvantages. Differences are usually in 
what the organisation is used to, not because one is fundamentally better 
than the other.
