I have to say that although I have seen a ton of concept phones, it
never crossed my mind that we could have shoulder buttons on the upper
corners like on a joystick or PSP/PS Vita. This great idea comes from
Benjamin Coughlin and it’s applied to a BlackBerry concept phone.
I must mention that I may just be wrong the touch strip could only be present on the side. I could serve as sort of a touch volume button. I can also see that the handset is slightly curved to the front. The UI on board points toward BlackBerry 10 OS, maybe in an evolved version…
