Baking Stone - Your Favorite Uses

Hey all,

I'm in the process of selecting a baking stone to purchase (or possibly two if it'll make a grave difference to put one at the top of the oven as well)... http://chowhound.chow.com/topics/798050

I've been doing a good amount of bread baking, and expanding the types and variations... I know that there are oodles of wonderful things to do with a baking stone, but curious as to some of your favorite uses and/or recipes. Also curious as to your experience in how having the stone in the oven full time changes the way other things bake.

TIA, and I can't wait til I nail which one I'm buying down, and get to playing and experimenting!
