The One Laptop Per Child project has revealed a design for a new machine - a slimline tablet.
Hardware designers at the One Laptop Per Child project went through several iterations and configurations before they settled on a final product.
The finished machine had several innovations, such as a sunlight readable screen and waterproof keyboard, and was made to be child friendly.
The OLPC project has not met its aims to distribute its machines but some nations, such as Uruguary, have taken them on.
OLPC produced a design for the XO-2 that made it more book like.
The re-imagined XO-3 laptop is radically different from its first incarnation.
What are these?
