Are there any such laptops available yet? I found Libretto W100, but this is a tablet, not a full-size laptop.

This is an idea that catched my imagination already a few years ago. You could display keyboard (with any layout you'd need at the second) and touchpad on one of the touchscreens and have some OS display on the other one (perhaps some virtualized OS, it would even have to be touchscreen-friendly one). Or you could turn the whole laptop around and display two pages of book or newspaper on both screens, etc.

If they are one day available at some reasonable price, I would love to try it out.

But typing on a touchplate? No tactile feedback and limited multi-touch capability. Perhaps for single finger typists it could be good Wink

I would have to try it to judge. I am not entirely convinced that tactile feedback it a requirement for efficient typing.
And Libretto W100 is said to have "haptic feedback" of displayed keys, but I don't know the details.

Are there touchpads that detect the force of the touch, in addition to the position? When I type I lightly rest my fingers on some keys without pressing. But if just any touch triggers a keystroke then I would have many false detections. Unless the haptic (vibration) feedback is precisely localised to the point of touch then it becomes too generic of a sensation.

However since the keyboard is virtual, I wonder if the software could be made smart enough to track the finger positions and adjust itself. Example, the F and J keys are generally used to centre the hands to the keyboard. But with a virtual keyboard the system could track the two index fingers and adjust position to match your hands. Although perhaps it would need more than just touch sensing, perhaps some video sensing also?

According to Moore's law, the retail price of such a laptop will be dropping to 2/3 of the original value one year after the initial release. Professor Grysztar, for the sake of these orphans, may I beg you for your patience to delay your purchase by one year and donate the money saved (i.e., 1/3 of that original retail price) to those less-advantaged children? Wink

I'm afraid that even the 2/3 of original value would still be far from "reasonable" from the point of view of average Polish salary. Look at the price of that tablet!

Tomasz, what's so cool about being a professor?
I mean, isn't it a waste of time? Smile

Not as much as requesting features without giving any reasons at all to implement them, other than "I'd like it"

Libretto W100, probably around $ 1000
no utility for the programming in assembly language,
so completely useless for me. Wink

@ouadji: According to that site Tomasz posted it is $1,320 and it has an Intel Pentium U5400 processor with win 7 home premium, So you could program for it in ASM Wink

@Tyler: I wonder if there are any short term effects caused by this, such as numbness in your finger tips, ect. I also wonder if it could lead to long term effects.

Just think about it, it is sending tiny amounts of electric to your fingertips, I think I will wait a few years and see if anyone gets sued, or complains Very Happy

Cody, there's always electricity running throughout everyone's body, AFAIK, electricity and hormones are the brain's only means of communication. If you think of it that way, it's like they're making use of the body's architecture to add new functionality, by enhancing the sense of touch.

revolution, about pressure sensors: A quantum switch could add pressure sensing to mobile screens.
