Think your cell phone is too heavy? Just wait until you can get your hands on a PaperPhone. Researchers at the Queen's University Human Media Lab in Ontario, Canada worked with the E Ink Corporation to develop a prototype (E Ink helped develop the technology behind Amazon to develop Kindle.).
Probably the most interesting aspect of this phone is that you bend it to execute commands called bend gestures.
It's paper thin.
