Re: LaTeX anyone?
I used to use it for things like equations, but now rarely do even for that. I'd only ever use it for scientific document creation / editing and these days I just use Word of all things. No, seriously. It's evil - but I consider it the lesser of 3 evils (LaTeX and OO being the other 2.)
It was more useful before decent WYSIWYG editors came about, now it just feels like writing in code when it's not required.
