I have been using this for a few days now, as a tool, more than a proper word processor... I don't do much worse processing anyway, as I prefer to write anything I do in a text editor...

However, it's very very good... it handles RTF files properly, it exports directly to a PDF file, which is handy, plus it's got it's own XML based file format.

Get binaries here:- Linux Windows Solaris (SPARC)

Mac OS X binaries coming soon.
