Seems the age of CD isn’t over; as Korea company Axxen is bringing back the original in mini form. Each Playdisc stores about 125 MB and definatly weighs significantly less than a box full of cds.
Playdisc runs on a single triple A battery, and the significance in this product, lies in the easier sharing of music. (Cant import music off of iPod as you can off a this or any other cd)

Player is built in.
