Playing the devils advocate, doesn't that apply to learning any new 
programming language - because there's always an inertia to 
overcome?  If you substitute Python for Matlab in the above, do you 
say it doesn't hold true?

One point that people always make when they've heard of Python is 
that "Python is slow, so to write simulations the students will have 
to learn <insert low level language> anyway".  I believe enough 
(informal) studies have been done to show that students with no 
programming experience learn programming faster using Python.

However, then comes the point that "Python does things differently, 
so it's harder to use another langauge".

 From the purists point of view I agree, however one criticism of the 
current course (using the department's own dialect of Basic) is that 
the language doesn't look good on the CV and isn't useful - something 
that Matlab may be able to overcome.

Of course a bigger problem is that the students don't want to learn 
to program in the first place ("We'd have done computer science if we 
liked computers").

Fantastic!

Search would be good.
