Talk about a concept whose time has come -- the pop-out joystick for mobile phones. From initial research, this design gets pressed in and turned to allow the 'enter' button in the middle of the d-pad to actually protrude from the handset for all those times when, you know, you need more tactile control
of those J2ME or Mophun games -- hey, you might even feel like you're on a PS3 (not). Regardless, this is an extra-cool development for the mobile space. For anything more than phone menu navigation (ahem, mobile gaming), we for one hope this concept comes to light in future mobiles, because you haven't lived unless you've fragged some folks on that 2 inch screen.
