The idea of Nokia U concept was simple – to gather collective thoughts and to create an ultimate concept design. Over 18000 votes will be counted to decide which of the three concepts should be included in the final render.  

So let’s see what we have done, there are many pictures of Nokia U Concept below:

This device may be equipped with a 4 inch touchscreen, USB 3 connectivity, Dolby Surround Sound, 8 Mpx camera and run multitasking OS. The dimensions of the phone may be 60x110x6-10mm.

These are the main features of Nokia U concept, but note that this is just a concept and there will be many changes before Nokia decides to work on it. Like in most cases, I guess, this concept is much better, than what we will get.
