Nonstick cookware or not?
I'm not going to get into the arguments back and forth about Teflon and its associated chemicals and whether you get them in your body from cookware or not.  I think there might be some risk, so just like I don't use aluminum pots (like my family had when I was a kid), I don't use teflon cookware.

I use stainless cookware because I like to be able to scour it clean, because there's tons of affordable stainless cookware with good thick bases to distribute heat evenly, and because if you use oil like grapeseed oil, you can heat it up enough that the stainless is essentially non-stick.  Also, you can use any sort of utensil with it, doesn't have to be silicon or wood, or a plastic spatula that might or might not melt.

Sometimes, when I'm doing an omelette I wish I had a nice teflon pan, but that's about the only time I miss it.  I think the only teflon I have left is in a George Forman-type grill that I use for bacon.
