I think I saw that PSP concept. It was like an old scroll, right? You'd pull the two edges away and the rolled up screen opens between, like the ancient paper scrolls. It's an interesting concept but doesn't seem very functional since the screen isn't rigid. The thing would flop around in your hand as you're trying to use it.

OLEDs are truely awsome and the bending concept with OLED's is a big idea.

Sony showcased a bendable laptop awhile back.

No one's made a concept yet, but if anyone remembers those snap wrist bracelets that were all the rage with kids a decade or two back, maybe they can adapt this OLED cell phone concept to be bendable with a rigid back like the snap bracelets.

And then there's OLEDs actually being put on your wrist, something the military seems to want for some reason.

And of course Apple is getting in on it, even though I don't see why this has to be curved.
