As someone who works in IT desktop support and management, I have one question about Windows 8 which I haven't seen anyone comment on yet.
What's the minimalist keyboard logout/shutdown/reboot sequence like, by comparison to previous OS versions?
On XP, it was 4 or 5 keystrokes: Win, U, (L OR (Home, Down) OR R), Enter.
On Win7, it was 3 or 4 keystrokes: "Win, Right, Enter" to shut down, "Win, Right, Right, (L OR R)" to log out or reboot. (Assuming the default hadn't been changed.)
What is it on Windows 8?
