I recommend a totally free office suite, which is Kingsoft Office FREE 2012. Kingsoft free office software suite is compatible with all the latest Microsoft Office formats. It can easily open, read and write documents created with Microsoft Office as well as a wide variety of other formats. Microsoft Office can also open Kingsoft Office files without having Kingsoft Office installed on the same computer. Kingsoft Office Suite Free 2012 is a free office suite that offers a number of features for creating, viewing and editing personal and business documents. Kingsoft Office Free 2012 includes Kingsoft Writer, Kingsoft Presentation and Kingsoft spreadsheets. These three reliable and versatile programs are perfect for both personal use at home and for professional businesses. They offer outstanding value at their listed cost compared to competing office programs.
And Libre Office 3.4 or Office Libre 3.4... also available for all, and not controlled by the big daddy that runs the company that controls Open Office.
