My Hope for the Future of Laptops

Way back when Natural Keyboards were all of the rage and gelled wrist rests were new, I was looking at the advancements in human interface input devices and started thinking about what my dream interface would be.
At the time there was this cool keyboard I saw advertised in the gaming magazines which had removable templates which would give you a themed lit keyboard. I was fascinated with it, what if instead of templates you could stick one of those really thin screens in there? Wouldn't that be cool? And what if it had some sort of touch interface to it? What if you could have programmed keys that you could reprogram and move around anyway you want? What if you could even raise the surface of the keyboard screen so you could touch type with it? Wouldn't that be cool?
The Idea I ended up with would have packaged it all up into a two monitor laptop with one defined as a screen and the other a keyboard. Then there would be a stylus for interfacing with the screen. You could type on the keyboard screen then pop up a different keyboard scheme for gaming, even have two sets of arrow keys for letting two gamers play at once.
I seem to remember making a little tiny mockup of the idea though I drew the keyboard using pencil and it had a track ball drawn on it as they were all the rage back then.
Later I started wondering why the screen should even be opaque? what if the screen was transparent and you could selectively make parts opaque or transparent/translucent at varying degrees. Then, what if you could even selectively make the screen reflective so a window could act a a mirror? Wouldn't that be cool?
Over time it has been fascinating to watch and see the advancements that have occurred to bring it closer to reality.
Screens have been getting thinner and thinner, more efficient and usable. LCDs now come in color and You can now look at from multiple angles. The advancements in OLED screens and color electronic ink display displays makes me drool at the possibilities if they could just be combined.
The advancements in touch to the point that it is now built into major operating systems around and with support for multi-touch it makes the dream even more interesting.
The only thing missing today is implementing a way to raise the surface of a transparent material so that it could be used to provide tactile clues and feedback for touch typers. [Update: This Brail E-book Looks Cool!]
I was excited when I found out OLPC was thinking along the keyboard screen for the XO-2. Microsoft working on the Courier tablet is excitedly similar as well.
Awhile back I read about a Sony VAIO laptop which has a transparent screen.
Now if the displays could also be 3D…
