Apple will use "Invisible Buttons" on its Devices

Apple will put this "new technology" to their new macbooks for 2011.

This buttons look invisible because they are made of the same material as the housing and you would not notice it is there until a light of the button turns on. This technology would replace the keyboard and even the trackpad on macbooks, making look better the design of the computer, and also making easier to write on the keyboard.
