I just received my Mac OS 10.5 aka "Leopard" Install disk. I tell you, the packaging alone is worth the $129 : a gorgious hologram on the front cover, and another splendid one at the back, appearing through icons and apps' windows. At the back of the DVD holder, those simple words : "Designed and engineered by Apple in California". That explains everything. Design in first place, no "inc." after Apple's name, and California, not "USA".
