Maybe I should expand about why LaTeX is so important to me. I use it as my main text processor, not only because it produces nice maths. It allows to abstractly structure a document (e.g. by defining environments that give meaning to a paragraph, like summary, conclusion, proposal etc), it allows you to define new commands (like functions), variables, conditionals and much more. For me, LaTeX is something in between writing and programming, where content is strictly separated from the layout. That's why I especially like to use it for any creative activity, where a lot of ideas are floating around, which can not (yet) be forced into a consistent document. And alone the possibility to add comments in the source is indispensable.
