Have I never mentioned Sun Microsystem's OpenOffice before? OpenOffice (aka OOo) is a free (of charge) suite of office software, very much like Microsoft Office. You can download and use use OpenOffice free of charge at www.OpenOffice.org. I use OOo 1.9 for Cathy's laptop.
Google has been making strides to become... something... more, and has been pushing Microsoft's buttons. Anyway, Google and Sun are partnering on OpenOffice. The download will likely be slow with the news, so give it a couple of days.
