Closing the lid on a Windows laptop and being 100% confident it won't decide to wake up either in the middle of the night thus feeling the room with an eerie glow - or in your backpack thus cooking the motherboard.
I'm sorry to say this is an issue everywhere. I've had a mac BSOD from unplugging a dock (doing it while the computer's suspended is/was a surefire way to trigger this particular bug), and linux is even more picky since it depends entirely on the hardware underpinning the dock.
