These things are complex enough that few people understand both well 
enough to be sure that all the stuff that has evolved in their company 
over many years would port over easily to something different.  And they 
tend to have a vested interest in keeping that stuff working...

If you have one server doing one job and you are starting from scratch 
you can think that way.  On windows, people have generally been forced 
to work like that because things break if you don't.  On unix, you'll 
find ad-hoc mixes of jobs that have evolved over decades all running 
happily on the same box.  In that scenario it is much harder to move to 
something that is not completely compatible.
