The current native solution, NeoOffice, is still much more robust and stable, but OpenOffice.org is making clear strides into a native OS X port.



NeoOffice
I made the changeover to Open Office on my office PC, which meant that I had to find a version for my Mac at home. I chose NeoOffice and am happy with it so far. I'm not sure I'm up to the job for Alpha-testing right now, so I'll wait for the regular Aqua release.
