The Glass Smart Phone/Tablet is a concept for the future smart phone; edge to edge, and totally transparent.
It has front and rear facing 3D cameras for tracking motion of both the scenery and the user. Together they can create fully tracked augmented reality, and couple with a 3D screen that needs no glasses, everything will look as if it is actually there.
The screen is also totally transparent. All the electronics are held in the tiny multifunctional on/off button, thanks to advances in microscopic electronic components.
