Just received my 2.4 Santa Rosa platform MBP (Rev D) from Amazon today. I started it right away only to find that there was Tiger running....I looked through the rest of the package and noticed that there was Drop-in DVD for Leopard installation.....a few questions: 1. Is this common for all Rev D MBPs or is this one really really old? 2. My Leopard DVD was scratched and sealed that way....is this something that I should be worried about? it appears to read the disc (going through the disc check as I type this). Should I ask for a replacement? I am glad I finally upgraded my G4 powerbook.....I was using ThinkPads in the meantime, but I wanted something newer than my T61.
