We are moving to a touch world, your average monitor in a year or two will be touch sensitive. People will go back and forth between keyboard/touchpad(or mouse) and the touchscreen.
Computer users want touch monitors as much as they want 3D TV, as in, they don't. This is just tech companies forcing things on the consumer.
I'm all for touch on phones/pads, but I don't think many people want greasy finger prints and arm ache on a large size stand up monitor.
