The present invention provides an extensible mobile electronic device with a housing, having a first housing element comprising a first front surface and a first rear surface and a second housing element, comprising a second front surface and a second rear surface. Said first housing element, and said second housing element are extensibly supported to each other, such that said first and second housing elements can adopt a retracted position and an extended position with respect to each other. In said retracted position said first housing element and said second housing element are located substantially on top of each other, said first rear surface conformingly adjoining said second front surface. In said extended position said first housing element is displaced with respect to said second housing element and at least a section of said second front surface is adjoining said and flushing with said first front surface.
