Update: Another really good one.
When we arrived at the Las Vegas airport, one of the baggage carousels had a monitor displaying a Windows error report.
When we got to the hotel, we passed a monitor with a BSOD.
This morning, on the way to the keynote, we passed several monitors that indicated each room's schedule. One had a BSOD, another was flickering the old "You have unused icons on your desktop" tooltray balloon.
