"I still have that half-second grace period to nudge the mouse and not need to punch in the password to unlock it."
You know you can change when the monitor suspends and set that differently as to when you are prompted for a password? I use Start8 and avoid Metro on my desktop, but it's amazing on my tablet. The problem is that Windows 8 needs to detect when there is no touch input and act accordingly, or let Metro apps run in a Windowed mode. Duh, add an exit, minimize, maximize button to the metro apps. Add a small drop shadow like the Zune desktop application has. Some of this stuff is common sense, and is what is really holding Windows 8 back from being amazing. Hopefully "blue" fixes this.
