You have:

Applix
Quadraton Cliq
Smartsoft
KOffice
Gnome Office apps
Star Office
Corel Word Perfect and upcoming siblings

Here are some open-source additions. A few of these (such as Abiword)
I actually _use_ on occasion. The others are just hanging around on my
Debian "potato"-based laptop in case I ever need them. For most of my
needs, I'm a vim / Mozilla / m4 / python / bash / awk / grep kinda guy. ;->

[...]

Abacus (small, easy graphical spreadsheet)
Gnumeric (spreadsheet)
Oleo (spreadsheet)
Siag Office (includes Scheme In A Grid spreadsheet, Pathetic Writer word
processor, Egon animation program, Xfiler file manager, each of
which is also available separately).
Xspread (simple X version of the old "sc" spreadsheet)

- Spreadsheet: Gnumeric, StarCalc for Linux/Windows compat
(I hate Excel,

If you have a mixed Windows-Linux world, it's StarOffice. It's
word processor, StarWord, is adequate (just like MS-Word, but I'm
biased because I HATE word processors, period), although its
spreadsheet, StarCalc, really sucks (at least on Excel conversion
-- Gnumeric is 10x better).
