I can never remember the free software that replicates a lot of Microsoft Office tools, but found it again today in a Lifehacker blogpost, so I'm reposting it here to never lose it again! OpenOffice.org describes itself as, "the leading open-source office software suite for word processing, spreadsheets, presentations, graphics, databases and more. It is available in many languages and works on all common computers. It stores all your data in an international open standard format and can also read and write files from other common office software packages. It can be downloaded and used completely free of charge for any purpose."
This software is one of Lifehacker's "61 Free Apps We're Most Thankful For", which is a good read in itself.
