I don't think we comment. I like free cash flow. So I guess I would put it this way, Lee, that we would -- where we see opportunity to make free cash flow long-term, we will continue to do that. And that could be a CapEx expense, where your cash flow would go down. For example, we bought the 61.5 degree Rainbow satellite for $200 million in the fourth quarter, so cash flow went down. Having said that, we think that for the next 15 years, we're going to more than make up that $200 million in cash flow utilizing that asset. We also believe that, we would hope that we would manage our business to free cash flow. And we think, to have value as a company, we have to have more positive cash flow than negative cash flow, obviously, in the future. We are unique -- the cable guys haven't done a very good job with that, and I think we focus on that a little bit more. We don't focus on EBITDA as much, as an example. And we don't call EBITDA free cash flow, so we are not trying to be funny about it. We can't cash flow the same way you would in your checkbook at home -- how much money did you start with and how much money did you end with? We know we have got to end with more money to have value as a Company. As far as economics of a customer, in general, the economics of a customer -- we think that there's upside. There hasn't been a lot of change probably in the last couple of years, but we think there's some upside. We think HDTV, we think some other services, we think the new portability things with PocketDISH -- depending on how we secure the signal and depending on how programmers that we work with try to monetize that, we think there's some opportunity there. We think that on the international side, we continue to have opportunity. We think that there's other services we could sell. We have a relationship with the customer, so the fact that the customer knows us, if we can find other ways to -- and they trust us, how could we grow that relationship? So there's upside there. There's some negative trends. I think the bundle that the cable and phone companies have is a factor in stealing good customers away from us, where the customer love DISH Network but they want a broadband, phone, all on one bill for $99. They do steal some good customers from us from time to time. So there's some negatives to the economic of subscribers, as well. And it's our job, and it depends on how we execute and it depends on how other people execute. It's our job on balance to make sure we continue to grow those accounts. And we think there's some positive ways to do that.
Carl Vogel: I think there's more opportunities to increase our revenues than there has been in the past, both in the HD interactivity and some VOD applications. But, as we discussed on this call, the investment in MPEG-4 and DVR and HD costs a little bit more money, but we think that the customer will likely stay with us for a longer period of time, as long as we have the complement of content that Charlie talked about in HD. I think the other thing that we need to continue to do and that we're very focused on, and that's leveraging the operating infrastructure. So, to the extent that we can increase the revenues of the added-value services, retain the customer longer with the enhanced features of the set-top box, leverage our operating infrastructure and lower our variable costs, I think the economics of the subs are pretty good, even though you might have a slightly higher investment over time. So, as I look at it, I think we have a lot of bullets in our gun on the revenue side. We have some opportunities to leverage the operating infrastructure and we still have a product that 330,000 net subscribers decided they wanted to be a DISH customer in the fourth quarter. So I think it's reasonably good at this point.
