"The first key item in this wearable PC is the PC itself. A device like this needs to be small, pocket sized preferably, with a good battery life, a reasonable amount of power, and a good feature set. Years ago, such a device was a pipe dream, given that batteries, processors, and even the so called "portable computers" were really anything but portable, powerful, or long lived. Yet if you look around you right now, that's exactly what we have. Powerful, portable devices with good battery life. Take for example your cell phone. Typically, most modern cell phones have more processing power than most PC's from the 90's could ever dream of. Even your iPod or PMP likely has more power than they did."
