Lyx - Consider it, if you like LaTeX!

I have been using plain LaTeX for my longer documents for several years now and I have been quite happy with that. Sometimes it was a little bit challenging to get the result I wanted, but in general I could do pretty much everything I wanted to. I prefer stable layout and clean results over WYSIWYG, so I never really thought about an alternative to plain LaTeX. But now I know, you can combine both worlds and get a thing that lets you write your diploma thesis or whatever without any stress. It is called Lyx, it is free and runs on most operating systems.
