Edges

I always like to look through the catalogs that arrive in my mailbox, even though I rarely order from them. One item I have seen recently is a brownie pan that is either zig-zagged or has three seperate rectangles. This is to make sure every person's brownie has chewy edges. Are chewy brownie edges really that high in demand? I am a middle of the pan girl myself. Maybe I am in the minority. What is your favorite region of a pan of brownies?
