here another "bad" creation from me..
-the Dual Touchscreen Display Slider Phone, the e680s(slider).
main touchscreen screen 480x320res
slider touchscreen 640x240res
that means for e.g. on the main screen shows the sms/text/email editor and the slider screen shows the virtual keypad that can be use with the fingers (like on the iPhone virtual keypad)
another e.g. is man screen we can see the movie it self and on the slider screen there are the controls like play, stop, volume and so on...
another e.g. main screen the web page, slider screen the browser buttons..
