We have always said that somebody should create a palm like devices that contain a processor/apes, monitor of the sort, keyboard and mouse. At the 2003 ITU Telecom World exhibition held in Geneva, the Tokyo-based NEC Corporation shows a theoretical $30,000 prototype of what they called a “Pen-style Personal Networking thingamajig Package,” or P-ISM. As NEC described the P-ISM:

P-ISM is a thingamajig package including five functions: virtual keyboard, a very small projector, camera scanner, a pen-style cellular phone with a handwriting data input function, and personal ID key with cashless pass function. P-ISMs are connected with one another through short-range wireless technology. The complete set is also connected to the Internet through the cellular phone function. This personal thingamajig in a minimalistic pen style enables the final ever-present computing.

This product allows you to work from anywhere in the world and have everything that you need at your fingertips. We all know that enough processing power and tri-wireless modes (Bluetooth, 802.11B/G, and Cellular) can fit into small devices (PSP, Treo’s). NEC only adds a viewing device (the projector) and an input device (a laser piano) to carry us to miniature-mobile computing. We know the input devices already meaning since see in the picture below (although this devices causes numbness/pain in your fingers because you are typing on a hard surface) at the present can’t we just get a smaller projectors. Oh and of course, for this to be worth anyone’s $$ I believe it will require to have a battery performance time of 6+ hours.
