What is the difference between the Leopard Retail DVD and my System DVDs in terms of what apps come with them? I know iLife is only available on my System Disks, but as I have iLife 08 discs, I can install that separately. What other apps will be missing from the Leopard DVD? I really just want to do a clean install from the Leopard disc, no upgrade or archive and install. I just feel that a new OS should deserve a clean slate.
