I love my new smart phone but miss the feel of keys

For the persons who love theier new smartphones very much and miss their feel of keys on their finguers here is a tech from Tactus where you can both touch and do feel your keys on the fingure sound good right? then wait for this tech a year and you could get this on your phones and other touch accessories. Well this consists of a tiny layer of fluid that deforms it to produce buttons of a given height, size and firmness. They act just like a regular keyboard, but disappear back into the screen when no longer needed. 

They already demonstrated its touchy-feely screen on an Android tablet at the Display Week conference in Boston. Do already this tech was tried by both Microsoft and Nokia too didnt work to the grit hope this will.
