If this proves as promising as the demos look the new Microsoft Surface II means doomsday for a lot of other multi-touch products out there, especially for the DI kind. Like the old projection based Surface they need a lot of space behind the screen. The new Surface uses a LCD with infrared sensitive pixels developed by Samsung and is only 4 inches thick. The raw image from the device, as you can see in the demo video, looks pretty much the same as from a camera in a DI touch. But as the diffusion layer of the back projection screen is missing it is pretty sharp. This allows to use the display as a “scanner” and should extend it usability for object and tag recognition.
