Ask HN: any alternative to MS word as a word processor?

http://www.openoffice.org/ - OpenOffice, pretty much the gold-standard in open-source office suites. Very similar to LibreOffice, since they are both descended from the same original Star Office code.

For the Mac, the free Bean word processor (http://www.bean-osx.com/) works for me!
