This document describes a pen-style computing device called P-ISM that allows for ubiquitous computing. It functions as a portable personal computer through a pen that acts as a CPU and projects a keyboard and monitor on any flat surface. The pen connects to the internet via Bluetooth and cellular connectivity and includes features like a digital camera, battery, and virtual laser keyboard. The document discusses the product, pricing, placement, target audience and merits and demerits of this novel pen-based computing device.
