I love the incredulous attitude of the Mac zealots. I've used MacOSX since 2001 and didn't know most of those commands, I'm sure they're all listed somewhere on my MacBook, but I wouldn't know where.What are you talking about, try cmd+shift+q to log out and you can restart buy cmd+control+eject.
Sleep is cmd+alt+eject
Shutdown is cmd+alt+crtl+eject
Also it's interesting to note that the new style keyboard released today throws a couple more issues into the mix. Even desktops will now need to use the ctrl+fn+F2 combo to access menus as the brightness key has been assigned to the previously empty F2 key. And I note that the keys that previously had symbols, like the alt key no longer do. How is new user supposed to find their way round when the key combos are hard to find displayed and when they are sometimes show sybols for keys that don't have those symbols?
