my favourite piece of technology

I think my favourite piece of technology is my mp4. I bought it 3 month ago, I had one but it was stolen.
I use my mp4 a lot,all the days, when I go to university or to home,whenever I come out I carry it with me. It was saved in pockets of clothes because it is very small.
 I like the mp4 because I can listen to music all the time, to an excessive volume to disconnected me  for a while. My mp4 serves me much when I go out running  or skating, I feel that motivates me more or distracts me from the tiredness.
If I didn't have the mp4 in my life everything would be more boring, the music is important to me and the mp4 is my way to listen this. My mp4 is also to save information.The only thing missing is to have a voice recorder.
