My 4.5yo has been using iOS since a bit before 2, has his own ipod touch and uses the family 1st gen iPad. He came home from kindy excited by using a PC. I couldn't understand it but now I do. Kids love to learn and he needs new challenges and this is another thing I can do with him. I have been waiting until he has better literacy to start on the cli, but perhaps the cli will help him learn letters and typing. Nice one.
