Samsung has recently filed a patent for a clamshell cellphone which can transform into a 2600-style controller...This is quite new and mostly aimed at people who spend hours playing their favorite cell phone games and im not talking about the game snake...Games grow more complex each day that passes thus making it hard to play using the all time classic keypad. That's where Samsung's engineers step in. The basic premise is that the bottom half of your flip-phone would pivot not only open and closed (or backward and forward), but also left and right, thus allowing you to escape from Blinky more quickly, jump over barrels more deftly, and generally get a serious game on.
Lets just hope that this can result in something truly easy and fun to use and that more cell phone manufacturers try the same.
