Tell me, why not?

I happily write entire reports in Eclipse (using the LaTeX plugin). I just write, put some markup where I need it, and when I press a button, a perfectly marked up PDF comes rolling out, with TOC, lists of figures and tables and image captions without me having to do anything for that. And if I'd need to write a book, I'd do it in there too; certainly not in any word processor.

To write text for a novel, you don't need anything more than Notepad.

Writing a book in Word or Writer and then generating an epub is like designing a website in DreamWeaver's visual mode and generating HTML: it's frustrating, and renders near incomprehensible code.

The same goes for using Finale or Sibelius for music. After getting used to the Lilypond and Frescobaldi combo (which basically is a music counterpart to epub+Sigil, or LaTeX+Eclipse, where Finale and Sibelius are akin to Word and Writer), you will wonder how you did without it.
