So you have a lot of experience with Microsoft world.  The Open Source
world is a different slant.  That might contribute to your
frustration.  I just looked up R, and I see it is for statistics,
which is something you also seem to know about.

I think there will come an 'aha' moment when python clicks for you.
Or maybe not.   Its a very well constructed language.

Good luck, though.
