I am reminded of the "lifetime" warranty on some old Ethernet cards.

If the card failed after 2 years and you called to enquire about the "lifetime" warranty, you were informed that the warranty was for the life of the card. Since the card died, it had reached end of life and was therefore out of warranty.

I don't recall the brand name now off the top of my head, but I remember that the company I worked for at the time bought the cards from the local CCA office/store. CCA ended up replacing the cards -- at their cost -- with those of a different manufacturer. Gee, wonder why?
