I think having a heterogeneous environment is a good thing for a lot of
different reasons, not just because it makes malware propagation more
difficult but also because it forces people to think about the compromises
being made in their implementations.

It also means that people developing more complex systems based around a
computer (like a DAW for instance) have more choices. Often those systems
have requirements which are very different than those of "general purpose"
computing appliances and it is good to have such choices available when they
are needed.

No argument -- in principle -- but isn't Windows+Mac+Linux sufficiently
heterogeneous?
