Only yesterday I tried OpenOffice 3.0 final. It is a mega release of OpenOffice in many ways. Even it was the much hyped release of OO.o. Overall it seems a complete overhaul of the venerable open source office suite. There are dozens of new features and improvements.
Of all the improvements and additions what I liked the most are:
1. Support for MS Office 2007 file format
2. Multiple page preview in oowriter
3. Notes in the margin in oowriter
4. and almost a dozen of other niceties.
