The designer Antoine Brieux has designed a special device called the HTC Tablet Tube, consisting of a 10-inch touchscreen with 6400 mAh battery and a card that contains all of the rest of the hardware that can be extracted and inserted into an envelope with a screen and a smaller battery to turn into a smartphone.

HTC Tube Tablet is interesting and technologically feasible, but perhaps the cost savings of such a solution does not compensate for the added convenience that you get with two independent devices.
