NEC is working on a concept PC, called P-ISM, that uses five different pens to make a computer. One pen is a CPU, another a camera, one creates a virtual keyboard, another projects the visual output and thus the display and another a communicator or phone. All five pens can rest in a holding block which recharges the batteries and holds the mass storage. Each pen communicates wirelessly with the others
