Cell phones are great, but one of their limitations is the size of the screen, which of necessity has to be small. To get around this problem, engineers have been for years toying with the idea of building a projector into the phone so that images can be displayed on any nearby flat surface. Unfortunately, until now, such phones proved too bulky for users to accept. Now, however, Samsung appears to have jumped that hurdle as it announces the Galaxy Beam, a new, small, thin and lightweight phone that has a projector built into it that allows users to project whatever is on the screen onto any nearby surface.
