In truth, it does take a bit of a change in your habits when cooking on Cast Iron; scrub immediately with water, no soap, and keep the curing process going by applying more oil.
Having made the switch however, I can say that I will never go back to non-stick or metal cookware; i enjoy cooking with lower heat settings while these puppies keep all the heat locked in and evenly spread out.
You can follow the link I provided in my Return of Cooking on Cast Iron post to learn the main reasons behind the switch.
