Hey, iron is fine... We use 'um... Just not the right pan for every job... Nice little 10" teflon fry pan saves energy, and is easier to use for lots of stuff like sautein' veggies, or fryin' an egg... Heat faster than cast iron and cleans quicker...
But you wanta fry up some chicken then nuthin' better than the ol' cast iron...
Like I said: different pans do different things...
