Back in those days when I was in High School, phones were not allowed in the school premises. The lectures were sometime so deadly that one can survive the atomic war but not the class. So my sister bought me an Apple Ipod Nano.
It become the thing in my school and I become popular in a very little, and every one started to like the device. It was producing the best sound with clear beats and long battery life. Easy to hide and use, so on one could catch. Still today after 7 yrs its still s good as new.
