Dell has a multi-touch monitor in the pipeline
The SX2210T is rocking many of the same specs as the touchless SX2210, including HDMI, DVI, 2 megapixel webcam and microphone, but has lost a few USB ports, presumably to make room for the touchscreen technology. The tech support article for the touch technology specifies it relies on the touch support in Windows 7. A USB connection is required for touch, in addition to the video connection.
The monitor is tilt-adjustable, but I’m guessing not enough to make it a decent alternative for Microsoft Surface or a multi-touch Cintiq. Still, I’m sure some enterprising person could come up with a mounting solution to make it more useful.
