I've been happily doing my postgrad in compsci, using the excellent LaTeX for all my papers and thesis. I got a job in medical research... holy shit... all the publishers require Word documents. Moving from LaTeX to Word is like moving from Python to Fortran on punch cards.
I agree with you, LaTeX is awesome for what it is commonly used for. No question there. However the learning curve is much higher than that of Word. So I think complexity and readability wise to an average worker, LaTeX to Word is more like Fortran to English.
