There is some cool technology/dreaming being shown there..... but, I am Not going to use any technology to check my work schedule while I'm brushing my teeth. My work day does not start until I'm done with my morning, um, ablutions - I don't care how important the meeting or cool the technology.
I like the idea of putting your smart phone down to activate the table top displays. It bypasses the insecurity of having a room full of people watch you type your credentials. It also defines the initial area of display. If the default setting (perhaps set in the phone?) is, for eg, that the phone defines the top right corner then both the table top display know what the other wants.
I wouldn't want to read a book on something with the weight of a few sheets of paper. Too shaky (hand-shake). A book's weight uses inertia to absorb these very minor tremors. They may be minor, but they are fatiguing if you are trying to hold a page up for extended reading.
