Some functions can be clunky: OpenOffice doesn't have the massive development cycle and resources that a major release from Microsoft or Apple gets, so there are some rough edges. For advanced users, there are dozens more tools behind the scenes. For basic word processing, number crunching, or creating presentations, the apps in OpenOffice offer everything you need, front and center.
Streamlined interface: Some open source tools can be intimidating to use, but OpenOffice has a straightforward and feature-loaded but accessible interface. While it may not have the same sleek, modern look as the most recent editions of Microsoft Office or iWork, OpenOffice can easily handle all the same types of documents and tasks. OpenOffice can open all of its counterpart's file formats and runs a smaller module. Near-complete tool set: Apache OpenOffice's biggest selling point is that it can almost completely replace Microsoft Office.
While bugs are bound to be an issue, this is an all-around powerful, accessible tool set for anyone who needs productivity software. With open-source development, features constantly change and improve, which makes OpenOffice in some ways more flexible than its paid counterparts. Apache OpenOffice is a free office-suite alternative to Microsoft Office or Apple's iWork Suite.
