It seems as if the $100 laptop (give or take a few bucks) has been discussed forever, but the first ones appear to have finally been built and shipped. The One Laptop Per Child (OLPC) project says it has received its first 10 from Quanta, its Taiwanese manufacturing partner.
The project is still in a beta stage, as the first 10 "B1" laptops were hand-assembled before a larger 900-unit run, according to the OLPC Wiki. Pictures were also available on the project's news Web site.
The B1 laptops run Linux and come with AMD's Geode processor, 128MB of memory and 500MB of flash memory for storage. It's not clear how many color options will be available for the devices, but maybe green will be the new black (or gray).
