All true, but do remember EDA cards do have a term life to those as well. Those are kind of three-year engagements, so some statistics for you, I think 43% of the customers in the current statistics use them faster than expected, and 70% use them equally or faster than expected. That's great. Over that three-year period, and if you go back and track through our Analyst Day, you will see that we showed how that stacks over time, and amounts to not only using the technology value of the card up sooner, but probably building on in a bigger way. But you still got to get near the end of the term to be able to do that, so if the card length was three years, and they use it up in two and three quarters years, or two-and-a-half years, you still got to get to the two-and-a-half years. Second fact, we started doing the things about two years ago, and so the end of '08 is when we start to see some of the first renewals of those things and really stagger into the beginning of '09, if you look at the momentum of them as we reported it, and so we've got good objective data looking at the utilization, and we're just beginning and really coming into the end of year, looking at the re-up rate those things, both in timing and value. I think we have a lot of confidence that they are going to get used faster and hopefully be of equal value, and we have some confidence that in many cases they're going to get subscribed for more value the second time, which is coherent with what we said at Analyst Day. So we need to get through another six months or so, maybe nine, to really see to get two quarters worth of stuff to make a trend, but what I am confident in is that the conversations we have with customers are more objective and factual based on information of utilization than conjecture and subjectivity, which has been the history, and that's the thing that's most interesting about the EDA cards. I've just came from all around the world. I can tell you big customers and small all around love these things because of the objectivity of it, and they buy the stuff at the rate they want to use it, and if they short call a shortfall, they don't mind paying a little more to be able to do that. And so that's the goodness of that mechanism and is not that you misunderstood, you just got to give a little bit more time to play out, but I am still very optimistic about it. Kevin.
