I feel like this could be a great thing but the way it's presented doesn't convince me that it is. Is the gtar an instrument for making music or is it something to help you learn to play a real guitar. If it's the latter then how does it compare with other learning methods, what are the advantages etc. If it's the former then it would be nice to hear how it sounds and what it can do. Other than the last few seconds of the video I have no idea about what the thing sounds like.
