 I mean, if you look at, I mean, you obviously have digital music and now you have e-books, you know, gaining some traction finally, and, you know, those are models that you could argue or quasi-cloud models and increasingly may become cloud models where they're, you know, where you're tied to a device, you're tied to a certain kind of software, et cetera. So it can, it can happen. But I think that, you know, what data portability is the key there, right? And, you know, at Google, we have a group of engineers who call themselves the Data Liberation Front, and basically they're working on ways to make sure that when you're using Google Cloud Services, you can take your data and go somewhere else, right? And that's pretty critical. And I think that we'd rather have that model where we've got to be really good or else people are going to, you know, go someplace else than try to keep people where they are. And from a legislative standpoint, I think, you know, it seemed, or a regulatory standpoint, it seems like the approach ought to be to encourage companies to take that approach as opposed to one that keeps people locked down. But there's no question that it's a danger. Thanks very much, David. That was a very broad speech. You will have an opportunity to put your questions to David at the Q&A after our other presentation.
