There is a Windows-based digital display in the grocery near our house. It is perpetually displaying some Windows dialog about the advertising program they have installed has failed/ab-ended in some manner. Seriously, I'm not sure the display has ever worked correctly (I go there a lot.) However, I watched the crew on a Virgin America flight announce that we had to "reboot" the plane because the entertainment system was frozen. It was, and everyone could see it -- it was Linux-based (not certain which flavor, pretty sure it was Debian-based though.) It had frozen, and all the screens (one for every seat) had a console stuck in some batch job and displaying the output to the screen. Luckily, we were still on the ground, so the reboot wasn't so bad. But it was alarming. Reboot a Windows-based advertising display? Who cares. Reboot the plane because the Linux-based system is frozen? Quite a bit more alarming.
