An electronic hand-holdable device, such as a mobile phone or Pocket PC, comprises a body, a screen for displaying information in an orientation defining a top and left and right sides of the screen, and a field of keys defining the numbers one to nine and zero and letters of the alphabet, and is characterised in that the field of keys is disposed above the top of the screen or to the side of the screen (Fig. 1). The field of keys can lie in a plane rotated through an angle &thetas; relative to the plane of the screen about the longitudinal axis of the device (Fig. 3) and the field of keys can have an inscription defining an orientation which subtends an angle α relative to the longitudinal direction (Fig. 1). In a preferred embodiment of a Pocket PC, the direction of writing on the screen can be changed depending on the orientation of the field of keys (Fig. 8, Fig. 10). |
