I want this. An Apple Keyboard that would allow me to connect my iPhone and use the screen as a control surface capable of showing buttons and small apps, like the Asus Eee Keyboard.
If you are not envious about the Asus Eee Keyboard-the 21st Century Commodore 64 with side-touchscreen instead of function keys-I am. The idea of having a small control surface next to my keyboard, one that would morph into different user interfaces depending on the application I am running-which could be incredible useful for both professional work, like having Photoshop shortcuts-and personal entertainment-like games or iTunes-makes perfect sense.
And then, when you add the idea of having small apps that I'm constantly looking at, but I don't want interfering in my main display, it's even better.
That's why I liked the tiny Mimo USB displays with touchscreen capability, like the one Jason reviewed. If Apple released this thing along some iPhone applications like NumberKey, I think they would sell like hot cakes.
We came across an Apple Keyboard concept similar to this. Instead of including a docking station, that concept had an induction charging surface-which I think doesn't make sense since, when you are next to your computer, you may as well dock-and a few OLED keys-which I don't think make sense either, since the iPhone surface could fit that role perfectly.
