Absolutely fantastic! I know a 13 year old autistic girl who does not speak.....but she can operated the TV and microwave. Can't follow directions, but simple commands like get your coat, put on your shoes, buckle your seatbelt are followed. I wonder if the Ipod would work for her.... She doesn't listen as well as the kids in the video, but you never know when something will click. Know for a fact she is frustrated.
Any child not speaking about 20 words by age 2 (even if they are only understood by parents) should be tested. School for early special ed often can start for kids as young as 2 1/2 to give them a head start if extensive training is needed, or at least to make sure they are school ready.
