I honestly thought, in the early days of the Smart Phone era, that some clever person would come up a way to have tactile buttons appear on the screen (& change with the changing UI). Whether it be a solution where the surface physically deformed or whether it be some sensory feedback due to electrical on our fingertips. Remember when you could answer your phone as you picked it up? Remember T9 input where you didn't need to look at the screen to type? Imagine a tactile solution on your onscreen keyboard but still being able to swipe... Imagine feeling where the 'answer' button was while you were picking it up and just clicking on it... :sigh: (Ironically, I was looking at the Nokia Classic series phones just last night)
