Our ARPU is still holding, it's the best in the industry, in the high teens, as you know, and first quarter was -- had no difference as far as that goes Most of the rest of the industry, and there's a couple other players, frankly, Inmarsat, Global Star and ORBCOMM, and I guess technically, Thuraya, all have some level of M2M business, as all our comp does, but it's part of the other's business. And I believe almost all of their ARPUs are in the really low single digits, low to mid-single digits. And again, that's not because of pricing or anything, it's just because we get utilized more often because our network works better than others. As far as margins go, I mean, obviously, service revenue represents extremely high margin for every dollar we generate there is as almost all margin. On the equipment side, we make money on our equipment and we make a number of devices. Again, the cost of those devices have come down dramatically in the last couple of years. So technically, the revenue is, from an equipment perspective, is kind of challenged because our newer products are so much less expensive than the older products, but the margin still remains very good on those because we're able to lower the prices and therefore, be more competitive against anyone else. And the overall M2M market is, as I said, I think you can read anything out there and you can see -- I don't think anyone would say that almost everything is being connected these days or being considered to be connected at some point. I'd say we're still in the very nascent early days of the M2M industry. We're still in sort of, what I would call, the experimentation stage. It feels a lot like it was like I felt like in the early '90s in terms of wireless voice penetration, you're seeing M2M penetration still early. And Cat is a good example of that is, they've been working this into their product line, but now they really are focused on a commitment to do 100% of the assets they make. And I think you can see all your automobiles are being connected, tracking of all types of assets and they're getting really less and less expensive assets to be tracked, but also monitored, railways and things in the air, and pipelines, and units of all types of things. So it's a very healthy early stage of that market. We think we're extremely well positioned to -- as that market grows, we'll do very well. And Tom, the latter part of the question.
