New Option for Augmentative Communication

Came across this new tool for augmentative communication called Tap2Talk. Seems like a nice alternative for augmentative communication. Watch the video for how it works. The positive features are: the price point, no Internet access is required, cool age appropriate tool and you can put in your own pictures and voice. One negative is that you do need sufficient fine motor skills to utilize a Nintendo DS. Perhaps you could adapt a stylus though. Any comments or thoughts?
