An office suite is a basic essential piece of software for the Knowledge Worker. For those of us who have spent many years on computers, there is now a free and OpenSource (FOSS) program called OpenOffice version 3.0 which does everything that Microsoft Office does including Spreadhseets, Word Processing, Drawing and Presentations. OpenOffice is compatible with a great many file formats including Excel, Word (including the latest .docx formats), Powerpoint which means that you will be able to carry on working on your existing files without interruption. If you have worked on Microsoft software before, you will find the interface in OpenOffice easy and intuitive although it is not as glitzy as the Microsoft product.

Have a look at the OpenOffice Website for further details and to download the suite.
