Totally off-topic, except for the EEPROM:

A colleague once told me about a bug in it's audi where it would write the current volume of the radio to an EEPROM after every volume change. So, after a few years, the car stopped remembering the last volume setting when turning the radio off and on, because the EEPROM died.

It's much worse: on every knob turn, modified value is written to EEPROM, and then real volume is set to value immediately read from EEPROM. So after some time volume control stopped working at all! (Audi Concert, Chorus)
