Most people hit the caps lock key by accident. It is particularly likely since it is close to the alphabet 'a' (often used in English and Latin languages) and just above the 'shift' key, which itself can be used in making uppercase.

I am willing to bet that 99 per cent of the world's users spend time deleting uppercase letters that have inadvertently appeared because they accidentally hit 'caps lock'.

You've said this is an education project, not a laptop project. What do you mean?

The goal is providing an opportunity for children to learn. What makes the laptop so suitable is the constructionist approach on which we are built. Learning by doing, peer-to-peer teaching and computer simulation are all part of the same equation. We all learned how to walk and talk by interacting with our environment, with real goals and rewards.

At about age six, we are told to stop learning that way and, instead, to do most of our learning by being told, by books or teachers, on a basis of, 'Trust us (adults). It will be good for you.' The laptop brings back a more seamless kind of learning.
