I was just going to say, we'll talk about that afterwards.
Of course, I'm here in my capacity as chair of the innovation committee, but I'm also happy to answer your question.
Yes, security will be paramount in the future. Not to toot RIM's own horn, but we do have an application called Protect Me that's available in the app world, so that if you do lose your BlackBerry, you can remotely wipe your device that has those credentials. Or you can find it via GPS as well, and you can make it flash and ring, too, as you want. Things like that will be very important.
You talk about interchange fees and that. I think there's a lot of opportunity in terms of micropayments, which will definitely bring down the costs for small entrepreneurs and offer some really interesting opportunities taking away from traditional systems.
