When my kids were at bricks+mortar school here (US), a lot of homework was project oriented for my 8 and 6 year olds.
Re: 'What's wrong with books'
Nothing is wrong with books, but personally, I don't have access to current information about science and geography in books. I have plenty of books but I don't have immediate access to info on all the religions, cultures and so on that we might want to know about. Being able to look at news articles that are relevant to our work is great. Or the weather... or where we are, earthquake activity!
Using Google Maps is invaluable for teaching geography. What can take forever to explain using globes and printed maps suddenly becomes much clearer when you can zoom right in on countries, landmarks and so on.
Also, my kids have been learning about programming with SmallBasic which is a great introduction to geometry, algebra and logic.
Of course there's no 'need' for a 6 year old to have a laptop or even to have computer access. But I don't understand all the smuggery about only giving one hour a week or no computers until 13. I agree that it sounds more like fear.
Computers are great. No-one's advocating spending 8 hours a day playing Call of Duty, but they give you access to so many tools and complement 'traditional' methods of learning perfectly.
