I come from a Computer Science background and i'm used to write my reports/documents in LaTeX. They look great and things like Hyphenation and kerning (using microspace package) are automatically treated. It looks way better than WYSIWYG editors like Word. I asked a Designer if he knew LaTeX and he didn't even heard about it.
What do you designers use if you want to produce professional quality reports, with minimum effort? I mean, for instance if you need to write a quick yet professional presentation letter. Smallest Effort possible.
