Issue 275: Bottom-of-the pyramid markets - the sub-USD100 laptop and the search for the holy grail
Never trust a man who invents Swatch Internet Time. Negroponte is a notorious bandwagon jumper, whose "ideas" usually melt with the snow.
The real story, in my opinion, can be found here: http://www.ndiyo.org/systems where an open source group are making a genuine, and well thought out, attempt to make a sub $100 thin client. They actually have a prototype, unlike Negroponte who has a press conference.
This seems to me like it might a) happen and b) be reasonably important when it does. They are based in Cambridge, so you might care to check them out.
