On the bottom left perimeter are the easily confusable microUSB and mini HDMI jacks (thankfully, Motorola clearly labeled each); on the right perimeter are
the red camera shutter key and the toggle that handles both volume and camera zoom.
What's interesting is that Asus has placed dedicated
camera functionalities, such as when you open
camera app, the volume rocker keys turn into Zoom - in and Zoom - out buttons, while there is a
red button on the right edge that lets you start recording directly in the default mode while there is physical
shutter button as well.
