I work with many kids on autism spectrum, and the use of ipods/PDAs has really made a fantastic impact on many of the school aged kids that I work with (not to mention their parents). I just wanted to share an an iphone application that quite a few of our parents are using now- it's called iCommunicate. You can find it in the iTunes store. It allows people to take pictures using their iphones (there are also pictures that come with the app) and turn them into customized storyboards/visual schedules. Thanks again for calling attention to such a useful piece of technology for so many people!
