Really obvious commentary here. It's pretty obvious that Siri is a shift in how users interact with their mobile devices but I think it's a little naive to say "The business model of Google is at risk" as if Siri is some unstoppable force that no one can stop. It's pretty dang new itself and to assume that Google isn't working on or doesn't have the technology to do something similar (and profit off of it via adwords) is a little ridiculous.
