Plug Shaped MP3 Player

Giha Woo from Korea designed an mp3 player that looks like a power plug. This design will help eliminate the need for power cables and allow users to plug in their music players directly into regular power sockets. This design looks so amazing and this creative idea can help other mp3 player manufacturers such as Apple can get some ideas. By the way, I hope, this gadget always need to be connected with the electricity and hence, we have to always be near the power connection. If it can have a power saving technology??
