>I wonder if in the future you could have micro-fluid channels underneath the screen where you can pump fluid to create raised bumps for the buttons. The problem with this technology is several-fold: 1) Areas that can be raised are fixed. 2) Liquids. 3) Do you like the feel of squeezing a zit when you press a button in a game? 4) Anything that uses this technology will not have a uniform looking screen, relegating the second screen to a sub-status compared to the first. 5) Microfractures due to repeated flex. 6) Scratches at 1 with deeper grooves at 2.
