Yes, and one can use LaTeX and achieve 100% with a similar one-time investment. I really don't understand this. To produce the document presented here LaTeX has absolutely no extra overhead compared with any other tool.
I suspect the misconception comes from the complicated looking tools like TeXnicCenter etc. If people saw me writing LaTeX in emacs (with zero buttons or other complications) they wouldn't think it was complicated. It's just text.
Still, if people insist on using Word for whatever reason I'm glad if they make the documents look nice like this one, even if the page geometry is way off (use Komascript).
