This is my concept. (sorry about the dodgy quality of the pic) The main idea behind this concept is that there are no moving parts to get contaminated with germs and bacteria. The device features a mirror like screen which is capable of displaying 3D holograms. On the back of the unit there is provision for the screws and camera lens to be hidden. Buttons on the side provide easy scrolling and navigation, as well as powering on/off the device.
