In these leaked slides, we get a glimpse at the BlackBerry 10 home-screen and media player UI. The slides detail how when you first unlock the BlackBerry 10 device, you see the last four running applications. Messaging is said to be the core of the home-screen. To the left you see all of your apps that you can start, and to the right those you have running in the background.
The media player has a nice skin. It also shows a smart feature and will have support for DLNA. On the same slide, it shows how the recent contacts list looks like. As you can see, the video chat capabilities will have deep integration with those who also have the capability appearing with a video chat icon in the list.
