"The cool thing is, while the market leading office suite vendor dropped VBA support and the Solver feature, OpenOffice.org recently introduced limited VBA support and includes a powerful Solver component.
"In addition, OpenOffice.org integrates well with the Mac OS X accessibility APIs, and thus offers better accessibility support than many other Mac OS X applications. Finally, people like OpenOffice.org 3.0 for Mac OS X because of its very good stability and performance. Reportedly, some Mac users have switched to OpenOffice.org just because of its extremely good stability, OpenOffice.org said.
The announcement also pointed out that not only is read and write support included for Microsoft binary file formats (.doc, .xls and .ppt) but OpenOffice can also open files created with Microsoft Office 2007 for PC or Office 2008 for Mac (.docx, .xlsx. and .pptx)
The OpenOffice.org group has said that they estimate the final release to be in mid September, 2008.
