Context menus in Metro
 

One tiny thing I wanted to mention about Windows 8: ever noticed how context menus in Metro appear above the mouse cursor instead of underneath? I'm assuming this is done because of finger input (by opening above, your finger and hand doesn't cover the menu), but with a mouse, it's just plain weird. Fun little detail though - shows you how much thought has gone into the touch aspect of Windows 8.
