Unthinkable CD player design

This Mp3 player also can play CD but wouldn’t it be cool if you had an MP3/CD player that will fit in your pocket. This cool concept shows a way that you could have the best of both worlds.This 'Dual Music Player' or DMP dubbed the “Butterfly Knife-esque CD/MP3 Player” will let you listen to MP3 as you normally would, hang it around your neck or clip it on your jeans. Just open its sides and there you are with a CD player.
Just pop-in your favorite CD and let it spin your CDs while exposed to the world. I’m pretty sure that while this is cool, but it could also be used as a weapon. Just imagine if someone pressed that up against you while the cd was spinning. Ok, it might not be lethal, but it would give you a nice burn.
