If my computer has a touch screen monitor, and I use the Xbox Kinect or regular webcam as my mouse with motion gestures, or voice commands having a Xbox Live Dashboard would be cool. It would be great to have a Dashboard instead of a Desktop on Windows.
I used computers which has tons of icons, files, folders, and widgets on a desktop which made searching for a shortcut very hard to find. Like the screen cap below
If it has a dashboard to separate each icons into a category related to what the program does, it would be easier to find by looking in the category the icon is related to which does not show un-related programs to the category.
