I cut soy out of my diet back in 2007, mainly because it's overly genetically modified and processed.  I don't miss it, because I wasn't crazy about it in the first place.
As this article points out, soy, in its many forms, can be found in loads of foods, even ones you wouldn't expect, like chocolate.  Not all chocolate has soy byproducts as an ingredient, but if you look at the list of ingredients, often times you will see soy lecithin listed.
