Samsung - Flexible display
Here's a short concept video exploring the Samsung flexible display. Obviously the first thing to note is that it looks sexy, that it looks like acetate and yet can do so much.
Unfortunately in the video the screen wasn't so flexible that it could be rolled up, otherwise I could see it being retractable like a scroll and put away in your pocket.
Not only is it flexible it's incredibly thin. Is this even possible? Where do the brains of the computer go? If this is possible then, we won't be far away from the electronic newspaper (seen in Microsoft's Future vision)
