Handheld Sudoku looks like cellphone

Now you certainly must say that this handheld Sudoku game looks pretty much like a cellphone, but what gives it away would be the monochrome display. The keypad is used to enter answers in lieu of a styles or other input methods. This input method reminds me of the good old days when the Game Boy Advance had some Sudoku titles of its own, with only the D-pad and the A button to help you progress through the game. It measures 52mm x 120mm x 17mm and retails for approximately $8.50 after conversion. Sounds like a pretty affordable alternative to me, rather than busting out the traditional pen and paper version.
