If someone has physical access they don't /need/ your passwords: they can simply boot the machine from a LiveCD and access everything as root - or just open it and remove the HD.
Mac OS X, by default, disables root - sudo's available, but you can't log in as root. 'Administrator' users (including the first user, by default) are in the wheel group, so they can sudo.
Multiple instances of X11, and switching between them, is certainly something that's been around *nix for years, but it's definitely beyond the install-and-forget kind of thing you're talking about. The big strength of Mac OS X isn't so much that it's introducing never-heard-of-features, it's that it's making them effortlessly to use.
