Have you tried the OpenOffice.org office application suite? I have tried this for 5 months now and I find this application having the same features with Microsoft Office, give or take a few details. What I like about OpenOffice is its documents are lighter in size than that of MS Office. For example, I downloaded the Book of Psalms from Claretian Publications in MS Word format and it is all of 512 Kb in size but when I converted it to Ooo Writer its size shrinked to 123 Kb and I was able to save 389 Kb disk space for other uses. OpenOffice documents can also be easily converted into Microsoft and Adobe file formats. One good thing about OpenOffice is it is free and you could download the 2.2.1 version from http://openoffice.org.
