Having gone down that path, I have to contradict this statement. OK, granted, 
there are a few quirks one has to get used to, but the fact that the whole 
system, from the hardest "real system-programmer" stuff to the development, to 
the end user is really consistent in the way things behave and are presented, 
makes it IMHO easy to grasp.

That is true.

This is no longer true. In the recent versions of the OS, there are numerous 
API's available to call from CL, COBOL, C, even Java, that do almost everything 
and anything.
