Buddy, you really need to do a little investigation before making statements like that. They make you look foolish. I have seen literally thousands of square feet of plastic laminate applied to plywood, particle board and MDF at a cabinet shop I am familiar with. Here is a link.
http://www.wellborn.com/ It was, and probably still is, the largest cabinet shop East of the Mississippi river. Contact cement is what they used. In fact, I don't know of a cabinet shop that doesn't use it for the purpose. Now you tell me how that is different from attaching Corian to plywood. You could pry off the Corian stuck with a few dabs of silicone with a screw driver. You will never get the plywood to separate from the Corian without breaking something.
