In my opinion, I think there are three devices which are the most useful: mobile phone, MP3 player and video recorder. First, we can see that everybody must have a mobile phone. What for? When you bring with you a mobile phone, it’s very useful to call your family, friends or somebody can help you when you met bad things. A mobile phone has a full functionality, it can help you almost in every case. When you are in danger, you get lost, you don’t know what to do with what is happening so you had-better use the mobile phone to request support. Second, today there are so many MP3 player are produced and sold for everyone in the world. They are small, medium handles, have many colors, designs and you have more choice when you want to but a MP3 player. Every MP3 player has a large capacity so you can dowload any music songs you like and put in it. It is somtimes has a small screen above the buttons, it is used to watch the video of the music song, we can see that it is very easy for us to listen to all the music that we want without deleting this old songs to dowload the new songs. The last one is a video recorder. We can see that when we go somewhere have beautiful sences and we want to record it. At that time a video recorder is very useful. Not only can you record the sences but also you can all the moment of your family. Or you can use it for recording something that you want. It is very easy to use and convienent for us to take with when we are in the trip.
That’s all about three devices that I think are the most useful.
