> In the WYSIWYG realm, there is hardly viable competition
I used LyX as a student http://www.lyx.org/. It was a great way to quickly generate a LaTeX document and then fiddle around with it at the end. That was the 1.5 version, they're now on 2.1 which looks much more polished.
Except that LyX is not a WYSIWYG environment, remember? LyX is a GUI environment that hides TeX/LaTeX macros and commands but it's not WYSIWYG. Remember that WYSIWYG means that what you see (on the screen) is what you get (on the printed page) which LyX most certainly does not do. Not bashing LyX, mind you, I use it myself and it's great.
The term Lyx uses for what it does is WYSIWM (What You See Is What You Mean) to describe the fact the GUI lets users manipulate the structure of the document.
It should be noted that LyX isn't quite WYSIWYG, which is actually a good thing. It shows you a rough representation of what things mean, rather than what they will look like, allowing you to concentrate on the content.
