DUO is a stylish and useful “pen” that is able to transform normal LCD (or CRT) monitors into touchscreen panels, with 22-inches being the size limit. Besides the model for monitors, there is another one made specifically for laptops, but that is another story.

Codenamed PMMA-01, the pen is compatible with the “Plug & Play” Windows Vista functionality, and supports a “Note Taking” functionality, but you must buy a separate device for that.

The DUO is available in black and white, and can be applied to any side of the monitor – left, right, top, or bottom.
