Not a new concept however it's awesome to see a working version of it! I don't expect to see Microsoft moving forward with it though. it seems that Microsoft likes to build prototypes that never make it into products, Google however is opposite they like to make products from prototypes. In the end I would be willing to wager that Apple is the first to implement this type of system in a consumer product.
