lyx is an advanced open source document processor. It produces high quality, professional output using LaTeX, but is far more than a front-end to LaTeX. No knowledge of LaTeX is necessary to use LyX, although it will give a user more power.
lyx-1.1.6fix4: description + notes
LyX is stable and fully featured. It has been used for documents as large as a thesis, or as small as a business letter. Despite its simple GUI interface (available in many languages), it supports tables, figures, and hyperlinked cross-references, and has a best-of-breed math editor.
Be sure to run "Option->Configure" if you have customized your LaTeX setup. The LyX Home Page has more information. Michael O'Brien's Scientific Document Webpage has some useful tips for improving the appearance of Type 1 fonts in PDF.
