Those splendid chaps over at NeoOffice have released the first completely free beta of version 2.0.
NeoOffice is OpenOffice with a Java-based Mac front-end; this means that you don’t need to run X11 to use it, and it integrates rather better with many Mac features – most notably the native Mac fonts and printing.
NeoOffice has been around for some time, but it is now based on OpenOffice v2, which means that it’s the best solution for Mac users wanting to embrace the increasingly-important OpenDocument formats.
