When I installed Leopard I did a clean install. After install I noticed that I no longer had some apps such as Garage Band, iPhoto, etc. Looking on the web I found that they are part of iLife. I knew that the iWork apps installed on my iMac were just a trail version and I made the mistake of assuming that the iLife apps were the same.
Recently on some blog post I noticed that it referred to iPhoto as being free and then it finally dawned on me was that I just needed to reinstall these apps from my Tiger install disks that came with the machine by simply selecting the Bundled Apps to install.
Well I guess I would have felt more stupid if I had ordered iLife.
