The basic principles about NUI is the removal of abstraction layers. If you want to click an icon you don't need to use a mouse or a pen or a trackpad, there is no exotic hand to eye coordination. You simply touch what you want to activate.

For instance my son who is 1 year have no problem interacting with the Talking Tom application on my iPhone.

If he garble something it garbles back in a higher pitch. If he touches the screen the cat reacts. He don't know what he is doing but by removing the abstraction and introducing close to real time feedback the iPad, iPhone and Android creates an instant feedback loop.

One can only imagine how this could be used to teach, train and remove the obstacles of interaction.

It is however not necessarily the best tool for serious creation so I guess that computers will fork into two main areas. Work devices with layers of abstraction but very powerful and the leisure devices with no abstraction but relatively less powerful.

To most people latter will be able to replace their laptops, netbooks etc.
