During the dotcom boom I ran a gift certificate startup. I needed kiosks for the upcoming holiday season. After searching for any kiosk manufacturer that used anything but Windows I had to settle. As soon as the kiosks were up and running the nightmare began. These things had six screens to capture data and a special printer to print MICR encoded gift checks. Every morning I had to drive to each store that had one and reboot them because of memory leaks, until the vendor supplied a script that would reboot them every night after hours. Huge opportunity to replace WIndows everywhere for these simple tasks.
