Title: Computer with a pen or touch sensitive display

Abstract: A computer with a touch sensitive or pen sensitive display is disclosed in which the position of the fully opened display has been designed in order that the torque typically applied to the top most pen or touch sensitive part of the display, in relation to a rotational axis about which the computer would rotate if it were to tip backwards, is less than that needed to cause the computer to tip backwards about that rotational axis. The computer is therefore stable even when the display is being touched by pen or finger, unlike conventional clam shell designs.
