Smart boards replacing chalk boards

Wired News reports on the rapid growth of interactive, computer-driven whiteboards in classrooms, which may someday make the punishment of cleaning chalkboard brushes a thing of the past. Right, smart boards are being used in more than 150,000 classrooms in the U.S, with even more being put to use in 75 other countries. The boards let teachers and students share assignments, surf the web and even edit video using their fingers as pens. And, by all indications, the market for the devices is booming, with more than a dozen manufacturers in the field, although one company, Smart Technologies, has a 60-percent market share.
