I mean just an AA battery compartment (hot-swappable would be great, though it may introduce some extra complexity). I'm not sure if they make control circuits for NiMH though.
A23 Cells or PP3 batteries (5-6V device, unless you want 4-5 AA or AAA cells). And yeah,there are lots of controller these days now. You can even remove the UPS unit from motherboards these days, extremely carefully.
We can make the stylus optional. It is only a simple plastic matrix with a 4 pin cable, usually embedded to USB, and as cheap as 10 USD. And since it detachable, you can place it anywhere. Of course I'll place a frame on it, to handle it, and prevent leaving debris:

But if you are going to ask for the pointing stick patent, send an anonymous email with the From address as chanprog@mailinator.com so that we can all see it at:

The current respondent is: patswip@us.ibm.com
And the place to make an inquiry if they do is:

Shower a kernel and a debian dev / done
I get your point. We do that AFTER we have the board designed. I know the LoongSon laptop was a huge success:

Not exactly, look at the updated drawing at [ http://i.imgur.com/2ktSfmb.png ].
Ah thanks. I get it. So it was

<LF> is implied, since I did <LF> them.
Also use postimage.org for longer images duration (since you can delete them at any time), or tiikoni.com/tis/ for temporary image; he even has polls: tiikoni.com/poll/
Another concern is that the LCD panel connectors must be extremely durable (i.e. support daily insertion/removal for years). The LCD cable should also easily detach from the LCD panel if forced without breaking anything (in case someone accidentally pulls on it).
That might be the most expensive part: a triple layer cable, with the last one being the actual tension resistor, and the actual cable and EM insulator underneath, being a tad longer than the resistive/reinforcing cable. The end ports on both sides will be a variant mini-DIN connector that is easily detachable, but it has an iris diaphragm latch on both sides (LCD and keyboard hub). The iris diaphragm is controlled by a small rotating hex graved hedge knob, with either of these drives: Mortorq, Robertson, TTAP, Bristol, Clutch, Torq-set (2nd fav), TA (fav), Tri-wing (3rd fav. SHARINGAN
!); making it compatible for human finger adjustments, and wrench and screw driver compatible (for the ones with bad fingers). Unless you want to use a rotational level, so fingers and pliers are ever used. I wonder if we should make all the screws similar heads... nah too costly.
Also you should look for an LCD screen that is at least partially reflective
Umm, just coat the LCD with any reflective plastic or tape. <5 USD. Heck, we can even use Acrylic glass (PMMA). Unless you want the LCD with a LED on the back as well (like everyone is doing). Swapable Coat? Unless there something else I am not understanding:

Finally the overall price shouldn't be over 400 USD, and preferably under 300 USD.
In a great group buy, that is possible. Unless you want to ask for funding out in the market.
Also, since there is no hard drive, there should be at least two SD card slots and default boot should be off SD. Internal NAND is a waste of money.
At the least a 1 GB hard drive for swap and temporary files, that has a special command to wipe itself. ExpressCard or CompactFlash? Unless you want to run everything on RAM. We do not want to expire SD cards which have the OS and the data. Waiting on Microsft to end their exFAT patent. Actually reviewing the wiki on Secure digital, it has DRM in place:

Why not make the slots then MMC?:
