It's a Miss!

Fabulous - I want one!  Voted a miss as they did not include headphones and there's no way it would have fitted in the pocket - did they have bigger pockets in those days?  It also must have eaten batteries like there's no tomorrow.  However, this idea predates the walkman by 25 years.  If you didn't like your records, you could have always used this as a circular saw!

In the early days of CD personal players, I remember seeing a similar idea, when the disc stuck out from the player.
