AbiWord 2.4.6 is a small, fast, cross-platform GNU word processor...and it looks to have the same goodies found on MS Word, including the ability to do footnotes, tables and cells. Loads of plug-ins, including import/export features, tools, utilities and dictionaries.
You can import documents from oOo, MS, Word Perfect and other formats, too. It's available for Mac, Windows, Solaris, QNX and 'nix users ...and the unix version is more powerful than the others.
