I was wondering if buying the 129$ Leopard release allowed me to install it on 2 of my machines. When I used to buy Windows XP disks, they sometimes came with the ability to install it on 2 machines... on the license certificate it would say 1-02 PC. So i was wondering if I could do the same. I'm new to the Apple world and I'm just trying to save a few bucks from buying the family pack (5), well because I only have 2 machines...
