And It's Easily Cleaned With a Bit of Microsoft Windex …

Microsoft (MSFT) started with a vision of a computer on every desk, and soon it hopes to put one on every wall as well.

During Microsoft’s 12th annual CEO Summit today, Chairman Bill Gates demonstrated TouchWall, a 4-by-6-foot multitouch computer that can transform home and office walls into computers. Gates calls TouchWall “the whiteboard of the future,” and it may turn out to be just that–if Microsoft can get it to market at a reasonable price. The company’s other multitouch computer, Surface, is currently shipping for about $10,000.
