Well, the One Laptop Per Child project is on course. They've got a few models out in the wild, and I guess this might be a promising review...but a kid of that age (and socioeconomic background) is already computer literate, not exactly the target audience for the project. But I still think it's a wonderful project.
Oh, and here's a review written by a 12-year-old - sounds like a pretty favorable review - not as much power as a "normal" laptop...but sounds like he liked the applications. And it's very well-written for someone that age. Hell, it's better writing than most adults I know!
