Hey, something different: Can the Win 8 aficionados explain to me what's intuitive about the log-in screen? Just about every mom & pop in the youtube videos and every reviewer so far was confused by it. Why exactly have you swipe that thing upwards with your mouse?

Since WinRT seems to provide a way to detect whether input came from touch or mouse:

You can work with mouse and touch input without knowing the origin of the input, or you can determine where the input came from if you want. [...] There's also a Pointer property that supplies PointerDeviceType information (Touch, Pen, or Mouse) and a PointerId of type uint

Wouldn't it make more sense to detect whether someone clicked with a mouse on the log-in screen and then make it disappear, instead of forcing unnatural mouse-swipe movements?
