If you look closely, you’ll notice that the phone is mostly air, like a building. Says the designer:
Thanks to the advances in technology mobile phones are getting smaller and thinner each year, however phones have to be a certain size for us to hold them and look at the screen properly. In my concept most of the electronic components are incorporated into the phone’s outer shell, but the size of the vertu phone remains the same size as it is now with empty space inside.
I think it’s safe to say that I’d much rather use this than a now-boring iPhone.
