Those design concepts are absolutely stunning, don't you think?
The problem with those designs is that the only transparency possible would be the cover, and you would see the internals of the hardware, and the battery…

Unless there's a transparent battery out there?
According to smartplanet, there is. This transparent battery was developed in Stanford University, could lead the way to having some transparent phones – that would definitely be awesome!
Until then, I will settle with a transparent toaster that will help me know when my toast is perfectly ready….
