I went to the Apple Store this Friday with a friend who was buying a new MBP. They told him that Leopard wasn't loaded on it, but there would be a drop in disc inside. Well, we got it back to his place and unpacked it, no Leopard drop in. Then I looked more closely at the system discs and the said OS 10.5. So we started it up and sure enough, Leopard. I just thought I'd mention it since some people here were wondering about Leopard being pre-loaded.
