Form factor (mobile phones)
A slate or slade (UK English) is a smartphone form with few to no physical buttons, instead relying upon a touchscreen and an onscreen keyboard. The first commercially available touchscreen phone was a brick phone, the IBM Simon Personal Communicator, released in 1994. The iPhone, which was released in 2007, is largely responsible for the influence and achievement of this design as it is currently conceived.
