Apple is in a quite peculiar situation with iWork. The office suite is so cheap that they probably make more money on people buying MS Office or Adobe InDesign from their shops. In other words, Apple needs to promote their competitors, because they make more money on the competition than their own product.
It will be interesting when they do so overtly. Imagine a product comparison at apple.com: iWork can this... MS Office can this... And then a long list of arguments to buy MS Office instead.
This peculiar situation may be part of the explanation why iWork is not as well maintained as it could be.
