I just installed iWork ’06 on my G4. I’ve only tried Pages so far, and I’m really disappointed. Pages 1 was quite snappy, without noticeable lag in scrolling etc. The new version is another matter. After starting it up everything sort of stops. When moving the mouse into the app, the pointer just disappears, and then reappears somewhere else, far away. Horribly sluggish. Hmm, maybe I should look into a CPU-upgrade?
