Believe it or not i have already thought about this gadget long before they even announced it to come out. And I am sure that Im not the only one. It was a very logical evolution of the mp3 toys. The Korean GumaHaworks company has some real potential for being on top of mp3 sales with this one.
It will certainly sell very well targeting the people that buy mp3s mainly for jogging.
The price for this gadget is unknown. Feel free to post it in the comments section if you find the price somewhere.
