This is weird. If this is just a keyboard, and I should be focusing my attention on a monitor, then all the eye candy on the keyboard is really a fail. Switching keyboards on the fly is pretty cool, but then the upper screen should be chopped off and the keyboard made smaller.
BUT if there is no monitor, then I have 3/4 of a touchpad devoted to a keyboard, and I can't see a lot of my work above.
Even the Timex Sinclair had a better viewing area: typing area ratio. The keyboard takes two tasks and makes them harder.
