Describe an electrical appliance you want to buy

I want to have an MP3, coz I think it will be the most functional electric equipment. At first, I can use it to listen to music. Since I am crazy about hip-hop, I have downloaded many songs from the website and store them in my MP3. When I have free time, I’d like to listen to them. Later, I will utilize some other useful functions of the MP3. Since it can record and play the voice. I can use it to record my spoken English. And then, I listen to it frequently to identify the grammatical mistakes I have made in my oral English. By doing this, I think I will achieve a great improvement in my English. Besides, I can also use it as a removable disk. Thus, I can copy some of the useful documents in my study from school computers. Based on the above benefits I have mentioned, I am eager to own an MP3.
