LaTeX made me learn Emacs. That was back when I used a Mac, which either says something about the state of the LaTeX tools for OS X in 2004, or perhaps that Emacs + AUCTeX is such a good LaTeX platform that it's worth using even when it integrates with the OS like a vacuum cleaner integrates with a dishwasher. Sadly, I no longer have any use for LaTeX, since I'm pretty much forced to use LibreOffice or other MS Word compatible word processors.
The UI in AUCTeX is friendly enough, but keyboard oriented. Try a few tutorials, and you'll soon find it's more efficient than WYSIWYG.
