AppleWorks is dead, soon to be abandonware.
It's a shame, really, because AppleWorks was so perfectly integrated. You could embed any of the document types within anything else, and it would work perfectly, with full functionality. Neither iWork nor Office can match that yet. On top of that, it was a single, small, fast application. Even on an old G3, it flew.
Besides, iWork doesn't have a database (unless you buy FileMaker) or spreadsheet yet.
