Who says the flip-phone is dead. Use it as a normal phone or watch videos without crouching over the display (and what video is rectangular anyway, a square display still give you all the size you need). Also scroll and control one display with the other.
Set the SlantPhone up sideways to show feeds while your at your desk
The cylinder hinge adds battery, cooling, and ergonomic capabilities to the SlantPhone that a typical smartphone doesn't.
You don't need a case anymore because the phone can take care of itself.
To really use it as a table piece let it support itself.
I will be 3-D printing this model of the SlantPhone just to see what it would be like in the real world.
The SlantPhone would also be separable. So that you could take a call with one half and browse with the other as if it were two devices. Each display is 3x2.5 inches.
Basically, a larger version of the SlantPhone. The SlantBook would not have a keyboard. Just two touch displays which allows for a completely dynamic user interface. After all a laptop is limited by its keyboard and mouse, a tablet loses half of its display to a keyboard, and a tablet with a keyboard is just an under-powered laptop. The SlantBook has none of the problems of those devices.
