         6 . The dual screen electronic device of  claim 5 , wherein:
 the plurality of document inputs displayed by the first display comprising the first touch-sensitive surface is an electronic alpha-numeric keyboard comprising a plurality of electronic keys, and   wherein at least one electronic key in the plurality of electronic keys is customizable by the user.   
     
     
         7 . The dual-screen electronic device of  claim 6 , wherein the first user interface displayed on the first display comprising the first touch-sensitive surface further includes an area configured to function as a touch-pad for manipulating a cursor displayed within the second user interface displayed on the second display. 
     
     
         8 . The dual-screen electronic device of  claim 6 , wherein:
 the second user interface displayed on the second display includes a user-composed document, and   the first user interface displayed on the first display comprising the first touch-sensitive surface further includes an area configured to display a portion of the user-composed document displayed on the second display.   
     
     
         9 . The dual screen electronic device of  claim 1 , further comprising:
 a second processor contained within the second housing and in electronic communication with the second display, wherein the second display comprises a second touch-sensitive surface, and   a second memory contained within the second housing and in electronic communication with the second processor, the second memory storing non-transitory instructions which, when executed by the second processor, cause the dual-screen electronic device to:
 while displaying the first user interface on the first display comprising the first touch-sensitive surface and the second user interface on the second display:
 responsive to detecting a second user input on the second display comprising the second touch-sensitive surface, changing a display of the second user interface on the second display. 
 
   
     
     
         10 . A digital camera system comprising:
 a digital camera comprising:
 a first housing, 
 an image acquisition subsystem contained within the first housing, the image acquisition subsystem configured to acquire a digital image of a field of view defined by a lens of the image acquisition subsystem, 
 one or more processors in electronic communication with the image acquisition subsystem, and 
 a memory, the memory storing non-transitory instructions which, when executed by the first processor, cause the digital camera to:
 acquire a live digital image of the field of view, and 
 transmit the live digital image of the field of view to a portable electronic device; and 
 
   a portable electronic device comprising:
 a second housing, and 
   a display mounted to the second housing, the display in wireless communication with the digital camera, wherein the display is configured to display the live digital image of the field of view transmitted from the digital camera in real-time.
