Nokia Morph
This little phone is a collaboration with the University of Cambridge, Nanoscience Center(UK) and Nokia. It can become a tablet pc, a wrist band, or just a simple phone. It can be morphed into 3 modes that include standard, bracelet, and landscape. Standard is a normal phone type of position. The Bracelet mode means you can use it as a bracelet and still have video chats. The landscape mode can be used as a tablet PC. The entire surface becomes a touch screen where you can watch movies, and check mail.
