When it comes to the price of manufacturing RAM, DSPs, and Flat Panel displays, how much of that cost has to do with chip packaging, marketing, distribution, etc?
Is there a type of RAM that can be manufactured so that the entire 8" or 10" wafer can be used at once? Is there some type of built in logic that can continuously check for bad memory regions, then route around them? Kind of like a Thinking Machine on a wafer?
By skipping the ceramic mount portion of the packaging, would it be possible to make computer that have all of the ram, parallel DSPs, and flat display circuitry combined: all manufactured and assembled simultaneously in clean room facilities?
For example, see MicroDisplay (http://www.microdisplay.com/). If these displays could be made the size of a Mead Notebook, with RAM and parallel DSPs all built into the same package, they could replace books, with excellent paper-like resolution.
Adding a flat battery and a radio (like a CDMA PCS cellphone with military GPS - see http://www.qualcomm.com/), with geographically variable spectrum allocation, they could be broadband books.
We could take the entire budget of the US Department of Education, and reallocate it to a manufacturing facility that produces these things.
If we put a MEMS fisheye camera in every pixel, this could also double as a vanity mirror.
