After decades of slow and glitchy message boards or an early Internet that ran on old copper telephone lines, the Twenty First Century introduced revolutions in both hardware and software technologies. Fiberoptic lines became the backbone of the new long distance networks, and wireless towers and nodes allowed the widespread use of distributed computing. Personal computers stopped being relegated to a floor in a room with a static screen, or to a still bulky portable platform you could place on your lap. Personal computers became handheld devices that could be left in a pocket while you walked around town. And for the first time in known history, people could communicate to anybody they knew, even to the other side of the Earth, while they walked around the mall or had lunch at a restaurant.
