Who needs a desktop PC? A powerful new crop of laptops makes it easy to hit the road. These mobile machines easily connect to the Internet via wi-fi or with special modems from cell-phone carriers. Since it's rough on the road, both physically and virtually, safety measures like personal firewalls, data encryption and rugged cases are now a major part of the mobile package.
