Sebastiaan de on the UI Changes in iWork / iLife ’09
Excellent analysis along with screenshots of the previous icons and new changes.
It’s quite clear to see by these images how Apple seems to have chosen a different style. It’s consistent between all apps; I also have some images of Pages’ old and new toolbar icon sets, but this side-by-side comparison of the Keynote preferences also shows the differences effectively (top icons are the new ones);
