I bet thats what a computer will be in the future... just a touch screen... no keyboard, or mouse... i remeber having an idea like this back in school for a project our idea was a desk that was a touch screen computer along with being a desktop... and instead of having books it would all be saved on your personal network drive and when you sat down you would put in your student id and all of your stuff would come up... this way you would never have to worry about forgetting books... and you could just have the teacher submit assignments to you via the network... no handouts, less clutter and no wasting paper for books or handouts...but i never imagined somthing like that.
