Your PC makes frequent mistakes and comes in last in the reviews, but you still love it. The computer locks up, screen splits eratically with a message appearing on each half blaming the other side for the problem. Claims that if you don't send it a million dollars, it's programmer will take it back. Makes sure that it's bigger than any other file. You know it's guilty of trashing your system, but you just can't prove it.
All files disappear, only to reappear very mysteriously a year later, in another dress directory.
