Yeah... it's nice that they're bringing this technology to the market so soon; but come on, how useless are Dell at demonstrating it?!
Just comparing that to earlier videos from Microsoft, showing mapping and photo applications enabled for MultiTouch, you can see from their silly little debug and drawing apps that they don't really have a grasp of it's true capabilites. Just wait until Apple gets going with this on their notebook range and forthcoming tablet device - that's when things will get exciting!
