Very true. I think many people don't realize how uncomfortable phone screens are because they are just used to it and love the portability.

The day I tried HoloLens I quickly saw there is much more potential in that tech than many thing.

A 360deg screen that you can take anywhere with you and that can give you a true field of depth / 3d view. When the devices will perform well enough and be portable enough, this will become huge.
