It is beyond laughable? What exactly makes it laughable? Are you saying no consumer would want a customizable and context aware strip of buttons? Sure auto-suggested words might be useless for many of us who type exceptionally fast. But how about safari (or Chrome, or Firefox) navigation aware buttons? What about text formatting options? You can't think of any use for a context aware multi-touch haptic strip on the top of your keyboard?
I have spent the better part of the last number of years trying to keep my hands ON the keyboard and AWAY from the mouse. This will allow me to do that in interesting new ways. I actually hope they make a full size external keyboard with the same functionality.
