Multi-touch-screen interface video

Description on Youtube:

Presentation by Jeff Han of a futuristic multi-touch interface during the Adobe sponsored TED2006. Jeff Han is a research scientist for NYU's Media Research Lab, and the inventor of an "interface-free" touch-driven computer screen. (Recorded February 2006 in Monterey, CA. Duration: 09:32)

I though I would not think that this could immediately replace a keyboard completely, especially in terms of speed (tactile feedback isn't something that can easily be replicated off of a screen, yet), this will definitely aid in replacing the mouse. And if it can also add in tablet-type functionality (like a physical pen, brush, and air-brush tool), it could be a boon for visual artists. Also, interactions by different users on the same screen would be possible with this.

Yes, I know multi-touch screen capabilities are not a new thing, but I like to keep up on this stuff. I do hope that the costs for this technology can go down fast enough so that touchscreens would be standard on consumer computing systems instead of the mouse. If you need an indirect control device for some reason (I.E., like for a first person shooter), then a mouse or joystick should be an optional component.
