An electronic device with multiple body elements is configurable to predetermined fixed portrait and landscape orientations each of which define a respective different operative position. A first panel overlies at least one portion of a main body element first surface and has a surface relative to usage and is arranged for sliding engagement with the main body, whereby in a first fixed configuration at least one portion of the main body element first surface is covered and not available for usage and in the second fixed configuration said at least one portion of the main body element first surface is uncovered and available for usage. A second panel overlies another portion of the main body element first surface and is arranged for rotational movement on the main body element parallel to the plane of the main body element first surface, whereby in the first fixed configuration the second panel is in a first orientation and in positional alignment adjacent the first panel and in the second fixed configuration the second panel is rotated on the main body element to a second orientation and in positional alignment adjacent the at least one portion of the main body element first surface. The main body element may be constructed with an arrangement of keys to carry out an intended function such as a QWERTY keyboard. A display screen may be constructed in the second body element and a key arrangement may be constructed in the third body element to carry out an intended function.
