Google adds StarOffice to its pack, its collection of free software. Though Star office costs quite a bit ($69.95), its free with the Google Pack.
Just beware while downloading as it has a huge installer (~140 MB), and it can be a bit slow during use. Comparison of features between various office apps here.
What I am interested though is, Google’s version of why it didn’t choose OpenOffice, the slightly stripped down LGPL version of StarOffice.
Note (17th Aug): The comparison page link given above compares various office productivity apps. Its pretty old (created in May 2005) and the versions reviewed in there are as of that date. Thanks to the reader for pointing it out.
