The other sensors on the market have multiple sensors and inputs. Today's article stated again it only has 2. That is on the level of a toy in comparison to the competition. This can only alow an up or down movement in a game. So this is very limited in what it can do. I really hope they are working on adding more in the next model. This cannot write an email or dial a phone number or even control a wheel chair. We are limited to games that only have 2 actions.
