 So we know it's really important that sometimes people are finished with their apps and they want to make, they just want to make them go away. And so what we've done is we've built an easy way. We just drag from the top, right, we get the stage and then you're just going to pull it down and it'll go away. And obviously this is a blue desktop there, so how can users change that? Well, oh yes, absolutely. So it's different to the developer. Yeah, we know that people care about, particularly as they see Windows 8 as a great expression of themselves, so we want to make sure that we give them a way to change everything that they feel super important. So here's an easy way for me to come in, change both the color, and this is reflected throughout the system. Is there any other changes that you're demonstrating today? Yes, well we've got... From the developer preview. From the developer preview? Yeah. We have a lot of mouse work. We have been paying careful attention to how Windows 8 needs to feel efficient and powerful when you're using it on a laptop. So we've built in a lot of ways to do things efficiently and fast and fluid with the kind of input that comes with laptops with the mouse. Okay, could you show me a couple of those? So right away you can see the difference between logging in with touch and logging in with the keyboard. I want to use my keyboard, so it's as fast as doing that. You can see that scrolling through the start menu when we do it with the finger, you would expect it to work one way. And of course with the mouse, you want to see things, you know, the simple, the scrollbar. You want to be able to use your mouse wheel to easily just go back and forth. You want to be able, I could just push on the side of the screen. You can see how easy that moves back and forth. So that feels right for the kind of input and the precision that a mouse is. In the same way, you want to expose the power of using your mouse and keyboard together, so to control the scroll wheel, find a quick way to see it. Now I can see my entire start menu, start screen, and I can easily get from one end to the other. And that's not in the developer preview at the moment, is it? I do not believe so. We're good. Thank you.
