Pages and Keynote do not provide equivalent functionality even to OpenOffice. That's not the target market.

If you're on OS X, you might as well just get Office 2004; it's somewhat nicer than the Windows version. Filemaker and Access are more-or-less equivalent, with Filemaker having something of a lower suck-quotient.

I thought that an example taken from a Samba list would imply a discussion about functionality on free platforms.
