The latest version of OpenOffice.org 3.2.0 has gained huge support due its increased speed. The high memory consumption during start up has been decreased; as a result many users are switching back to the free Office Suite.
Here is another development that will add more value to its popularity.
Portable version of OpenOffice.org is now available for download. Users can easily run the application directly from any portable device like USB drive or CD.
So, if you found it difficult to use OpenOffice.org due to lack of administrative rights, then portable version will be your best choice.
