There are a couple of rumoured features that "phones of the future!" always seem to have, and up there with flexibility is transparency. See-through phones have been a futuristic what-if for ages now, but now a company called Polytron is promising that the future is here! Or at least close. Within the year, perhaps.
Sure, it'd be impressive, but it just raises the question: why? Is there any really good application for a transparent phone? Even if there is, would it ever be useful for the average Joe, expect maybe if he wants to keep tabs on the palm of his dominant hand? Can you think of super-crazy-awesome application I'm missing? Would you really want one of these?
