You may have had the OpenPro CD which was not the Ceramic. The Ceramic lasts almost forever. I still have a pair in perfect condition after several seasons of wet weather use. The Ceramic rims needed a special green shoe or you'd go through half a pad in one ride. After a while the ceramic lost its initial sharpness and pad wear went way down.
Mavic has a new thing, the Exalith:
Exalith 2 | Mavic - United States
Don't know anyone who's running them, but worth a google. They also need special shoes. There was a fellow in England doing some specialty ceramic touring rims, but I don't think they worked out.
