This will not help you, but I thought a lot of people would find it very interesting. Calphalon now markets cookware in Japan and Australia that is anodized AND will work with induction cooktops.

I wonder how they do that. Perhaps a steel layer between the aluminum and the nonstick surface.

Here is a link that might be useful: Calphalon Contemporary Nonstick-IH

Thanks, deepwater. That was really interesting. I did e-mail Calphalon and they verified that the tri-ply they sell in the U.S. is not induction ready and said something like, "only our cast iron products will work on an induction cooktop." They said not one word about the product you linked. This is really too bad since I've really liked using my hard anodized pots and pans. They always look good and I'm not a pot scrubbing kind of person plus food cooks really well in them.
