OpenOffice.org programmers have released a very rough version of the open-source office suite that runs natively on Mac OS X.
The Microsoft Office competitor works on Linux and Unix systems using the X11 graphical interface, but the new version uses Apple's native Aqua interface.
It's alpha software, though. "This software may crash and may destroy your data. Do not use this software for real work in a production environment," the download site warns. And there are serious issues yet to be addressed: it can't print, copy and paste aren't fully functioning, and the software crashes after quitting.
