Art Lebedev showed off a concept of a touchscreen/keyboard with tactile feedback:
Optimus Upravlator is a completely new kind of input device aimed at the media professionals. It features a 10.8 inch color LCD (800 ×600 pixels resolution) with 12 see-through buttons occupying its surface. Each of them has five contact points—one in the center, top, bottom, left and right—which are freely assignable to user interface elements in the software of your choice.
An optional folding stand allows you to place the keyboard in the most ergonomic position and orientation available in your workspace.
