Engadget had this gadget:
"Yamaha's got a thing for making dreams into reality, and we must say, we're crossing our fingers and hoping to all that's good and merciful in this world that the above pictured device goes commercial. Little is actually known about the keyboard / notepad hybrid aside from the fact that it was showcased at the Milano Salone trade fair in Italy, and for what it's worth, Yamaha christened the device "key for journey." Look, there's even slots in the leather-bound lid so the keys have room to breathe when it's all closed up. Ah well, a boy can dream, can't he?" More info here
Maybe we can connect this to the Authorized Steinway.
