One of the cool tools which I keep about is a nifty office suite called OpenOffice.org. Derived from Sun's StarOffice suite, it's open source, and it's free.
And it's stylish: just look at the document icon to the right there.
That's right. As in, you don't pay a dime for it. You just have to download it.
There's a version for Windows, for MacOS X (requires X11 but if you have 10.3 or later you'll likely have that) and for Linux (requires Xwindows as well).
It's a suite that includes a word processor (Writer), a slide presentation editor (Impress), a spreadsheet (Calc), a vector drawing app (Draw), an equation editor (Math), and an SQL database (Base).
I don't need to use all that stuff but I have used OOo since about version 1.1.3, and it makes (at least for my needs) any MS Office completely unneccssary. It not only groks MS Office files, reading and saving as .doc, .xls, and .ppt formats, but conforms to the XML-based OASIS standard...any application that will read XML-based documents will talke to OOo.
This is a great app for those who want to de-MS thier home computers, those who need to exchange documents with Word users who can't get MS Office, or anyone who has a copy of Office that has, we might say, a checkered provenance.
Check it all out here.
At least, since it's free, it's worth looking over.
