I've just been at a presentation by Alan Kay who launched the $100 laptop yesterday. It's a small machine (for small hands) and even has a crank for power. But the most interesting thing about this product is the software that's being designed for it. Kay has some great ideas about learning. He pointed to a page on 'gravity' on wikipedia and said that although he likes the wikipedia idea, he doesn't like the way that the page is 'just a bunch of claims linked to other claims' and not a great way to learn about science. 'Science means you don’t have to trust the experts. It's exactly the opposite of religion.' He pointed to some incredible software that enables kids to test the theory of gravity themselves. Check out some of it here.
