It's going to be really cool holding this if it's not a fake. It'll be like gaming on a piece of glass.
I would be scared to hold it without a case, like the Xperia Z series, for fear of dropping and cracking the unit.
Although the discussion on this most probably fake render has dissipated, I enjoyed reading the thread with respect to the engineering discussion. It's fun and additive to read and learn about the possible ergonomics, engineering aspects and mechanisms in which this form factor could work. Thanks to everyone who contributed!
