IA tools for Mac OS?

[from drewspace] Andrew Hinton pointed this one out on his blog. Apple has this article about Mac OS applications for Information Architecture work. I can't wait, personally, for OSX versions of Illustrator and Photoshop to become available, and it's really a shame that Visio isn't available at all for the Mac. Sigh. I liked how they expressed the role of the IA, by the way -- "working with the client to identify problems and opportunities and then articulating the best solutions." Very high-level, but appropriate.
