Microsoft Experimental Adaptive Keyboard

One of the things that you really miss when you design for touch screens is tooltips on mouse-over. Nobody wants to look stupid, and mouse-over can really help users avoid pressing the wrong buttons, by providing more information about what they do.

A physical keyboard with real keys could still have a touch sensitive surface. Then you could have tooltips when you rest your finger on a button. This is not included in the Microsoft Prototype, but I like to dream. It's nice to finally see some serious adaptive keyboard hardware. Although I think I would prefer an e-ink screen instead.
