There's something to be said for the old T9 input system. Most often that something is "why would you use it on a touchscreen," but for a certain type of user it's extremely useful. Sharp is playing to those users with the unfortunately named Aquos IS14SH,  heading to the Japanese market in the near future. The odd combination of a 3.7-inch touchscreen and a full number pad is achieved by a bottom-sliding mechanism.
