I use Apache OpenOffice for complex documents that need formatting, and Gedit for casual typing. (Deleted every trace of LibreOffice. I know it's a fork of OpenOffice, but the bloody thing wouldn't stop crashing on me.)
I also play with the opacity of the text windows too, because a solid white page hurts my eyes after a while; I like being able to see my wallpapers while I type. ^^
I think I can hear the flak cannons now!
