To appreciate this iPhone 6 concept is to acknowledge that there really isn't much point in incorporating a button on the front face of the popular mobile phone. Such a feature robs the display of valuable real estate, reducing the potential length of the touchscreen interface.
Designer Antoine Brieux intelligently decided to move the home button of the handset to the upper edge, placing it immediately below the pair of volume controls. When you grasp the cellphone in your palm, it's easy enough to reach the switch with either your thumb or one of your fingers.
The iconic Apple symbol still appears prominently, but snugly, at the base of this NAK Studio iPhone 6 concept's screen -- a display that can now boast a 4.9-inch diagonal dimension.
