By all means bring the Laptop, it will come in handy, but I too don't see the need for the OS Discs??? I've never *HAD* to re-install either of my Macs, I've done it because I wanted to, or there was one or 2 little things that were messed up and I couldn't figure out how to fix them 🙂. It's not like windows where the whole OS just dies randomly and you HAVE to re-install, If your Mac can't make it a few weeks without a re-install I think it's time to call AppleCare 🙂.
