So far I was used to use some kind of office product to write the text and manage the literature directory, preferred a version of StarOffice or later OpenOffice. In 99% of all cases this is very suitable for writing letters and a short text with not to many pictures and drawings. But when text has a specific length, some more pictures/drawing or special directories (e.g. references, index, tables, literature …) is can get very tricky and you have to do a lot of manual workaround. And that is the point where LaTeX/ TeX is jumping in.
