We have been using this for about 2 years with our son, who is non verbal. It is way better then the PECS system we were using, because he was constantly chewing those up or throwing them away. I also like how customizable it is, I have been able to build in screen shots for all of his tv shows and episodes using the camera. However, I do think it would be a marvelous thing if TouchChatHDAACwWordPower included a more diverse range of skin tone colors on their representations of faces, body parts, etc. All of the generic forms not specific to a known celebrity are apricot colored. My son has beautiful brown skin. Non verbal children are a diverse group, and I think stick figure renderings don't take up much storage space, and can easily be colored in with more then one shade. I think children tend to feel marginalized when they do not see images that reflect them, and special needs kiddos are already a group at risk for feeling and being marginalized. It is also pretty frustrating that if your kiddo accidentally touches the "back" bar, it repeats every single thing requested since it was last cleared. It can really disrupt and disorient a kiddo with sensory issues. And for my son, who struggles with fine motor, he accidentally bumps it a fair bit. His aim is not always as precise as he would like, but it is getting better all the time... Just not enough to save us from back bar issues. Otherwise we LOVE how TouchChatHDAACwWordPower has improved his quality of life and his ability to tell us what he wants and to feel heard. And despite the monochrome skin tone, there is a decent range of object drawings, etc.
