a printed circuit board inside said housing enabling electrically connected to and said flat panel display and enabling said flat panel display to display computer output and selectively to perform independent computer functions, said circuit board comprising at least a microprocessor, volatile and non-volatile storage, and video graphics hardware for sending output to and controlling said flat panel display,

a connector for receiving power and output signal from a computer said output signal to be displayed on said flat panel display,

wherein mass inside said housing is distributed towards the primary handgrip.

14. The display device of claim 13, wherein said display device is operable in a first passive mode of operation and a second active mode of operation, wherein during said first mode of operation the display device performs as a display for another computer and in a second mode of operation the display device performs as an independent computer utilizing its own computer hardware for processing power.

15. The display device of claim 13 wherein said primary handgrip is physically larger in surface area than said secondary handgrip.

16. The display device of claim 13 comprising at least two tactile ridges disposed on each of said handgrips.

17. The display device of claim 13 wherein said primary handgrip and said secondary handgrip are contoured to fit a user'"'"'s hand and have only rounded edges to maximize comfort against a user'"'"'s hand.

18. The display device of claim 13 wherein said primary handgrip surrounds a battery which powers said display device, wherein said battery may be selectively engaged or disengaged by a user.
