Autism, Wii & The Classroom

I'd like to know if anyone has used the Wii with their Autistic children at home or as a therapy tool. Please post your pros & cons. I think the games are a great idea and would like to see more Wii's used in the classroom. Most of the Autistic children (well all children for that matter) are drawn to it. What a great way to teach social skills, opportunities to include the kids in mainstream activities.
