Transparent Smartphone Design

Polytron, a Taiwanese technology company, is developing a transparent smartphone design.  This transparent Polytron smartphone uses smart glass that looks opaque when turned off, but it will be transparent when turned on.  

In the prototype, you can see some of the components that are not transparent, such as MicroSD, speaker and battery.

I wonder how much this smartphone will be priced. And if they do available, it's interesting to see what kind of response Apple, Samsung, HTC, Nokia, Asus and other manufacturers will provide to counter.
