Well, that may work for you and your nonstick pan, but cast iron is a different story. I came to learn that it requires a bit more care and attention to maintain but if you give it some love, it'll never let you down.
But I guess if you're satisfied with your easy-to-clean nonstick pan, that's your choice. Just don't come crying to me when you have to replace it in a year or two because the coating has peeled off.
(never would've guessed that arguing about pans was going to be a big thing for me today!)
