An office regular--the white board--is going wireless, another use for the emerging Wi-Fi networking technology, which needs to pick up steam if it's to meet analysts' heady expectations.
Several companies have been souping up the tried-and-true but decidedly low-tech white board, taking it from a waxy writing surface for felt-tipped pens to a giant plasma touch screen linked to a PC and a projector.
The "smart" white board can display anything running on the PC, whether it’s a video or a PowerPoint presentation. Electronic "pens" have taken the place of the traditional felt-tipped variety, allowing users to write notes "on" the screen or to highlight displayed items. The newfangled boards don't come cheap, though, running anywhere from $1,000 to $20,000.
