Journal editors who accept LaTeX source from authors, desktop publishers/layout specialists who may know their field of expertise and are familiar with Word/DTP software, but not LaTeX syntax - it's more efficient to quickly fix a small item on-site and request the author's OK than ship the source back, have them fix it, take another look, send it back again, etc. Sometimes, you find an issue in the nth hour before publishing, so the ability to make a small change and get an assent makes or breaks getting that article into the run. Making scientific authors who include a lot of equations in their work use Word because the journal can't handle dealing with LaTeX is just cruel. :)
