I disagree.

I am not concerned about how many I have to learn. I am concerned about 
how many Cisco have to maintain, and the internal forces that having 
multiple choices will create.

There are plenty of large software suites that run on multiple hardware 
platforms, but without anything like the divergence that IOS and 
successors suffer from.

Still, I don't see the point in discussing it further - if you like 
having different IOSes, then I'm glad for you and things are fine from 
your point of view. I'm sure many are happy with it as well. However, 
from the responses to this thread, I'm not alone in my opinion either.
