http://www.amidasimputer.com/ The Simputer is a low cost portable alternative to PCs, by which the benefits of IT can reach the common man. It has a special role in the third world because it ensures that illiteracy is no longer a barrier to handling a computer. The key to bridging the digital divide is to have shared devices that permit truly simple and natural user interfaces based on sight, touch and audio. The Simputer meets these demands through a browser for the Information Markup Language (IML). IML has been created to provide a uniform experience to users and to allow rapid development of solutions on any platform. The developer kit relies heavily on Tcl/Tk for application development.
VK 05-mar-2005 while very interesting idea in principle (linux, and all that), FAQ says about availability as If all goes well, by March 2002 you should be able to buy one of them.
Looks like web site is way out of date, although some devices probably exist throughout the world.
