A few days ago, Pantech released a dual screen phone (main screen and touchscreen as keypad) named SKY IM-R200. As you can see in the image above, the OLED touchscreen keypad take a place at the bottom slider. The navigation that will display on the touchscreen keypad is an interface to give users virtual key or list of contact name, easy as that.
Boasting dual camera (2Mp & VGA with face recognition), the IM-R200 automatically vibrate when a key is pressed. Very good.
