I am currently using this device since 2011. this device has taken up in market very high. The most elegant features are

1. body design with 0.28mm thickness
2. 720p video recording
3.40 hr music playback
4.7 hr video playback
5. both sides camera
6. wifi inbuilt

most advantage of this device is that the battery backup. it has 15 hrs 40 min like no device would have it.
secondly the inbuilt A4 processor chip set is powerful that it uses little amount of power to distribute to its components. all most all games like fifa 13, COD and latest release games can be played on this. lastly I conclude that this device is one of the amazing and coolest device that ever made by apple.
