assisted communication devices -- any advice? Springboard Lite? Others?

[Guest guest]

My 2.7 year old son has suspected speech apraxia with hypotonia and some mild

sensory issues. No cognitive deficit. We have had an evaluation by our EI

services and have been in contact with the state about an assisted communication

device. We are looking seriously at the Springboard Lite device. Do any of you

have any suggestions or feedback when looking at specific devices? It appears

that this is the kind of device that would be most appropriate for my son --

both now and to grow with a little bit. I don't know if there are any drawbacks

to the devices that I am not aware of.
