The typesetting program LaTex has a bad reputation for being complex and people are put off from adopting it because of the steep learning curve. It's arguable that taming a traditional word processing software to comply with complex formating requirements of a journal publication or thesis is also quite complex.
If you are looking to make the switch, I recommend watching Dr Robert Talbert's Introduction to LaTex video series. There are a wide variety of LaTex editors available to make the task easier, popular ones include, TeXnicCenter, Kile, Latexian, and TexShop to name a few. If you are a Google Docs addict, ScribTex is your LaTex answer, or at least until Google maybe-hopefully-one-day-wouldn't-it-be-lovely provides its own on line LaTex solutions. Having a command cheat sheet at hand helps too!
Lastly, if you are in need of scientific and technical writing guidance, this collaborative website has excellent resources for both students and instructors. Happy Writing!
