  And he got a new one, so he can't run an old OS on his new laptop. So the old+old still works.

    But I can run an old OS on my new laptop. In fact, I can run many old OS's on my new laptop. I run MacOS 6 (using vmac). I run Windows XP (using Parallels). I even run old Apple II software (using VirtualII). But I can't run Snow Leopard (only Snow Leopard Server, which is not quite the same thing) because the license doesn't allow it, and Parallels enforces that restriction.

      >only Snow Leopard Server, which is not quite the same thing Well, it's hardly different. It's Snow Leopard, same kernel and userland and everything, PLUS a number of extra packages.
