iPad 2 and Mirroring Capabilities

Today a student brought in his iPad 2 and VGA cable, and.... we discovered that when we hooked the iPad up to an LCD projector, it mirrors everything that is viewed on the iPad.  I have looked online and spoken to representatives at the Apple store for the past several weeks, and no one seemed to know if the iPad would work with VGA as well as HDMI, so I was thrilled to find out that the iPad will work with any of our VGA projectors in the district. Whether it's an app, the internet, a video...anything, it will be mirrored on the screen.  It's a teacher's dream for instruction.
