Why is no one using Senseg tech?

I’m obsessed with true haptic feedback I think its game changing stuff. The technology is already there but no one is using it to make an actual product, is apple saving it for iPhone 20? If so why isn’t Microsoft using it? as Windows Phone could certainly use a boost in sales. Haptic feedback by that I mean true haptic feedback (not the screen vibrating gimmick) in my opinion has a huge take on the future on mobile computing.

Does apple think that it's not that big of a deal? Can you imagine how much better software keyboards are going to be with this tech? It could revolutionize the mobile gaming industry. Productivity apps will be much more practical to use.
