The absence of a numeric keypad on a laptop is sometimes irritating. But thanks to Canon’s new mouse it solves my problem and can also juggle with two other functions. The LT-100TKM has a clamshell like form factor, which when closed acts as a normal optical mouse at 1000dpi and makes numeric keypad and calculator function work after opening. It is selling in Japan for $32.
