Tucked away in Apple’s MacWorld keynote presentation was a little tidbit of particular interest to scientists. After years of waiting, our voices have finally been heard — Pages ‘09 includes support for MathType and EndNote.
From Apple’s site:

In Pages ’09, you can now create sophisticated equations for research papers, lab reports, and journal articles using MathType 6.1 Compose your equations with the MathType point-and-click equation editor and instantly add them to your Pages document. Pages also works with EndNote X2.1 Choose from over 3800 bibliographic styles supported by EndNote X2 and easily insert citations into your Pages document.

This is certainly a welcome addition, and will make Pages a much more attractive prospect for writing scientific literature. Hopefully Apple will also open the app to other third party developers, but I am not holding my breath.
