Without any doubt, the Smartphones of this current generation are simply powerful. They can now do several things you want it to do, and it allows people to carry a single device as opposed to before when a different device was required for each function. A modern smartphone can do almost everything regarding your daily computing needs: function as an alarm clock, camera, calculator, flashlight, gaming device, gps, photo album, web browser, video recorder, voice recorder, radio, word processor, and allow you to e-mail etc.
