In the last three decades of having the opportunity to learn and use TeX, i have managed to avoid it. In the same time i've helped a friend with word processing for her dissertation. I'm still not sure how we managed to get it to work with all the horror stories about data loss and Microsoft Word at the time. But it did its job and I'm still in the WYSIWYG camp. Maybe in another life...
You are still left with formatting equations, but Word lets us use Latex-ish syntax for that now, so you can keep the fine control of Latex within the GUI context.
Don't get me wrong, I hate Word, but it is required in many environments. Adopting a rational use strategy helps a bit.
