3M M2256PW gives touch to Win 7, more
3M today unveiled one of the first multi-touch desktop displays that supports more than two input points. The M2256PW has a typical 22-inch, 1680x1050 display but can recognize as many as 10 points, or two full hands, without an increase in lag. It's designed for Windows 7 but should work with any computer that can recognize the input.
The screen takes DVI or VGA for input and uses USB both for the touchscreen input as well as to take in peripherals. 3M hasn't detailed pricing or said exactly when it expects the display to ship.
