Currently there are ARM Cortex A8 tablets with 7" LCD's using the $5.00 Allwinner A10 ARM soc on sale for ~120ea.

The actual cost to build them is around $60 ea
Modules like these will support and industry of mass produced low cost devices that will interoperate with them. You'll be able to plug the cpu module into your desktop unit or set-top-box at home and surf the net, write stories, play games, hang out on-line, and so on. You'll also be able to take the module out of your desktop unit or set-top-box and plug it into your laptop unit and surf the net, write stories, play games, hang out on-line, and so on.
I imagine the reason that they reused the PCMCIA design is for reuse of the tooling for the case and also the durability of the connectors. The PCMCIA connectors have durability ratings of 10K insertions. Many card edge connectors have only a durability of 100-200 insertions. The simply made fascia plate keeps these new cards from being inserted into legacy sockets. The cpu card might be swapped from a laptop to a desktop, set-top-box, car PC, cluster rack, etc etc. You could make devices with a simple cover plate to keep the cpu module from being easily ejected if you wish. Devices such as laptops, set-top-boxes, etc might be easily upgraded to a newer or more powerful cpu or more RAM by simply swapping the cpu module.
There is a possibility that a design very similar to the BeagleBone will be spun with this new Embedded Open Modular Architecture/PCMCIA standard as well as other ARM soc designs. It will probably be at much lower cost than the BeagleBone $89 USD. http://beagleboard.org/bone
This new standard allows you to plug in whatever cpu module you wish that is compliant.
There have been several other "open" projects that were almost open. What will be open and what parts if any will remain binary only? Are there data sheets for the ARM SOC with complete register info? Will the firmware for hardware init and Bootloader be open?
The Broadcom BCM2835 looks like the ARM SOC used by the Raspberry Pi. There isn't a link for its data sheet that I could find. So it looks like just another closed hardware ARM design.
The NetWinder was based on the DEC/Intel StrongARM 110. They had quite a nice desktop working back in 1999 along with a large developer community
Portable ammonia factories could fuel clean cars
Edman Tsang, a chemist at the University of Oxford, is not convinced that the hydrogen needed to make ammonia can be produced economically using electrolysis. Fleming and Maxwell claim to have got round this hurdle.
A micron and a meter is a million times different! Why did that website use m for microns? Look at how much time this has already wasted!
He was using the symbol m vs the symbol for micron or micrometre. That is why it looked like he was measuring the wavelength in meters vs microns.
The site he was referring to is http://www.infrared-thermography.com/material-1.htm
They could have at least used um vs just m to be more clear.

If you have a procedure with 10 parameters, you probably missed some.
