Nothings is compared with the Cellphone with music. It´s like a notebook, you can do almost the same but keep it in your pocket. It´s like MP3, but you can do anything else while you listen music. It´s like a phone, but you can send texts or play games too. It´s like a camera but you can take photos without bateries. It´s all this together !!
I got my cellphone when my last cellphone broke, so I went to Movistar to change it (I have a plan in Movistar, so my cell costed $300 :P). I use my cell to talk, to send text, to play, to listen music, to take pictures, to recording, etc. I use my cell all day, although nobody calls me :(
I can´t imagine my life without my cellphone, well.. I can, but I love the music and I need be conected with the rest of my family and friends, so I think that have it is so useful :)
