After making whole world going mad towards i-phone and i-pad, now Apple is making some revolutionary changes to bring into market the unique i-watch. The front face of the i-watch would be either flat or curled. Sensors would determine whether the device was wrapped around your wrist and, if so, in what configuration and adjust the display accordingly. Along with other main features some that come to mind include pairing with the Find My iPhone feature, acting as a portal to Passbook and controlling third party accessories and home appliances.
There have been many rumors about Samsung is also working on a flexible OLED product in the marketplace within the next year. Only time will tell what features either of these products will have.
