Thats not an hp jack and a port, thats the power button, its in the same place it always is for Samsung phones. the right hand side at the top, which leads me to believe that the Nexus Prime has a chin like the Galaxy s and Galaxy S II (that thing on the left that everyone thinks is a camera), a little later in the video on the right there is another hump, I think that is going to be the camera. But I could be wrong, this is just what I see when I look at the picture because if it was the camera:
a) The camera would be on the bottom of the phone = stupid
OR
b) The power button is on the left side at the bottom = stupid
