We periodically discuss the advantages (and the few disadvantages) of cast iron cookware on Chowhound. Those who love it sing its praises while those who dislike it tend to heartily berate it.
I just discovered that one of my non-stick pans needs replacing. As I took it out of the cupboard I noticed my extensive collection of cast iron on the shelf next to the non-stick and it occurred to me that I typically find it necessary to replace a non-stick pan every few years and I've never had to replace any of my cast iron - some of which is over fifty years old. Just one more reason why I love that stuff.
Do you love it or hate it?
