Inaccurate title. It should read, "Why Do Companies Still Use Something I Hate?" Seriously, complaining that an out of disk space error message pops up on signs? I have a Slackware Linux box that has been running for years. Probably ran out of disk space a dozen times since I first installed it so I know from personal experience it's not immune from running out of disk space.
