I’m a huge proponent of LaTeX also, but I feel like it’s not that widely used outside of specific professional niches. The biggest issue I have with Word (and similar software) is the content generation _and_ typesetting being forced into the same interface. It just breaks everything all the time. I’d much happier using word if it only allowed you to type in an Edit mode, and only allowed you to change fonts and layout and stuff in a View mode, and the View mode changes weren’t reflected live in the Edit mode.
