Smart Phone- apple i-phone

The input of the device is that the users can keyin the word through touch screen. The musics, pictures and videos we like also can send to the phone through USB.

The ouput of the apple i-phone is that the picture we take can be clearly shown and the quality of the music is much more nicer.

The advantages of using this device is that we can see the picture and heard the music much more nicer and clearer. We can also play the games by using touch the screen.

The disadvantages is that the screen of the device will be spoilt if we do not take care of it and the users will also addicted to the games.

I think this device is useful to me because i always listen to songs and play games when i feel bored through the phone.
