iPhone 5 and an extremely interesting concept!

  Because for now we don't know what the future iPhone terminal will look like, here we have many concepts of the device. Today's by Mashable and he presents us an iPhone 5 built using liquid metal technology. The device is only 7 mm thick, a 4-inch screen, a 10-megapixel camera plus a 5-megapixel one on the front and 4 speakers. The device is interesting, but somewhat similar to this one iPhone 5 Liquid Metal concept presented a few weeks ago. Which one would you choose?
