The HTC P3470 is already very striking from its appearance, because it manages to get by with very few keys. To compensate, the device comes with a Touch Screen and stylus. A scroll wheel is available for scrolling, and two soft keys are used to navigate in the Windows Mobile start menu. This controlling method might take a little time to get used to, but it is also quite practical with many applications. And it guarantees that enough space is left over for a 2.8 inch diagonal screen, without making the Smartphone particularly large or unwieldy
