Granted, Motorola's latest patent application is really about a dreamy user interface system, but it's the allusions to a flexible keypad / display that really has our imaginations tingling. Put simply, the firm draws up plans to concoct rollable cellphone parts that have an "active and inactive" position. More specifically, a reservoir of electrorheological fluid could be used to stiffen the display or keypad when a call came in, and when the current was taken away, the phone could once more be rolled up and dropped into the smallest of pockets (or an M&M's Minis tube). A respectable idea, sure, but one that we definitely don't see happening here anytime soon.
