OpenOffice.org is both an open-source product and a project. The product is a multiplatform office productivity suite. It includes desktop applications such as a word processor, a spreadsheet program, a presentation manager, and a drawing program, with a user interface and feature set similar to those of other office suites. OpenOffice.org also works transparently with a variety of file formats, including those of Microsoft Office.

Evo Networks recomends OpenOffice as an alternative to Microsoft Office only in cases where casual use of a productitiy suite is needed or there is minimal interaction between OpenOffice users and Microsoft Office users. Download Here.
