I purchased iWork '08 when it first came out. Things are working pretty well for me, I haven't used all of the features yet. I do have one problem, Numbers runs slow and there is a noticeable delay from when I type a number and when it actually appears on the screen (or any other action I do). I am running all of this on a 12" PB G4 1.5ghz with 1.25 gb ram and 10.4.10. Has anyone else had this problem? Is my little Powerbook not powerful enough to run numbers? Any ideas on how to remedy this issue?
