Swiss designer Matthias Pugin has just solved an issue with sliding phone, by changing the sliding mechanism a bit, as you can see in the images below. The innovation comes through the t02 concept phone, that’s small enough to be hidden in the user’s palm.
But you won’t see any sliding surfaces or steps when it’s open. It looks as it is meant to be open. The black piano finish gives it a classy look and the unusual key pad and the big display give it a modern touch.
